W83697HF/ HG
1. GENERAL DESCRIPTION
The W83697HF is evolving product from Winbond's most popular I/O family. They feature a whole new interface, namely LPC (Low Pin Count) interface, which will be supported in the new generation chip-set. This interface as its name suggests is to provide an economical implementation of I/O's interface with lower pin count and still maintains equivalent performance as its ISA interface counterpart. Approximately 40 pin counts are saved in LPC I/O comparing to ISA implementation. With this additional freedom, we can implement more devices on a single chip as demonstrated in W83697HF's integration of Game Port and MIDI Port. It is fully transparent in terms of software which means no BIOS or device driver update is needed except chip-specific configuration. The disk drive adapter functions of W83697HF include a floppy disk drive controller compatible with the industry standard 82077/ 765, data separator, write pre-compensation circuit, decode logic, data rate selection, clock generator, drive interface control logic, and interrupt and DMA logic. The wide range of functions integrated onto the W83697HF greatly reduces the number of components required for interfacing with floppy disk drives. The W83697HF supports four 360K, 720K, 1.2M, 1.44M, or 2.88M disk drives and data transfer rates of 250 Kb/s, 300 Kb/s, 500 Kb/s,1 Mb/s, and 2 Mb/s.
The W83697HF provides two high-speed serial communication ports (UARTs), one of which supports serial Infrared communication. Each UART includes a 16-byte send/receive FIFO, a programmable baud rate generator, complete modem control capability, and a processor interrupt system. Both UARTs provide legacy speed with baud rate up to 115.2k bps and also advanced speed with baud rates of 230k, 460k, or 921k bps which support higher speed modems. In addition, the W83697HF provides IR functions: IrDA 1.0 (SIR for 1.152K bps) and TV remote IR (Consumer IR, supporting NEC, RC-5, extended RC-5, and RECS-80 protocols).
The W83697HF supports one PC-compatible printer port (SPP), Bi-directional Printer port (BPP) and also Enhanced Parallel Port (EPP) and Extended Capabilities Port (ECP). Through the printer port interface pins, also available are: Extension FDD Mode and Extension 2FDD Mode allowing one or two external floppy disk drives to be connected.
The configuration registers support mode selection, function enable/disable, and power down function selection. Furthermore, the configurable PnP features are compatible with the plug-and-play feature demand of Windows TM 95/98 , which makes system resource allocation more efficient than ever. The W83697HF provides a set of flexible I/O control functions to the system designer through a set of General Purpose I/O ports. These GPIO ports may serve as simple I/O or may be individually configured to provide a predefined alternate function. General Purpose Port 1 is designed to be functional even in power down mode (VCC is off). The W83697HF is made to fully comply with Microsoft PC98 and PC99 Hardware Design Guide, and meet the requirements of ACPI. The W83697HF contains a game port and a MIDI port. The game port is designed to support 2 joysticks and can be applied to all standard PC game control devices, They are very important for a entertainment or consumer computer. The W83697HF provides Flash ROM interface. That can support up to 4M legacy flash ROM. The W83697HF support hardware status monitoring for personal computers. It can be used to monitor several critical hardware parameters of the system, including power supply voltages, fan speeds, and temperatures, which are very important for a high-end computer system to work stably and properly. Moreover, W83697HF support the Smart Fan control system, including the thermal CruiseTM" and speed CruiseTM" functions. Smart Fan can make system more stable and user friendly.

6. HARDWARE MONITOR
6.1 General Description
The W83697HF can be used to monitor several critical hardware parameters of the system, including power supply voltages, fan speeds, and temperatures, which are very important for a high-end computer system to work stable and properly. W83697HF provides LPC interface to access hardware . An 8-bit analog-to-digital converter (ADC) was built inside W83697HF. The W83697HF can simultaneously monitor 7 analog voltage inputs, 2 fan tachometer inputs, 2 remote temperature, one case-open detection signal. The remote temperature sensing can be performed by thermistors, or 2N3904 NPN-type transistors, or directly from IntelTM Deschutes CPU thermal diode output. Also the W83697HF provides: 2 PWM (pulse width modulation) outputs for the fan speed control; beep tone output for warning; SMI#(through serial IRQ) , OVT#, GPO# signals for system protection events. Through the application software or BIOS, the users can read all the monitored parameters of system from time to time. And a pop-up warning can be also activated when the monitored item was out of the proper/preset range. The application software could be Winbond's Hardware DoctorTM, or IntelTM LDCM (LanDesk Client Management), or other management application software. Also the users can set up the upper and lower limits (alarm thresholds) of these monitored parameters and to activate one programmable and maskable interrupts. An optional beep tone could be used as warning signal when the monitored parameters is out of the preset range.
6.2 Access Interface
The W83697HF provides two interface for microprocessor to read/write hardware monitor internal registers.
6.2.1
LPC interface
The first interface uses LPC Bus to access which the ports of low byte (bit2~bit0) are defined in the port 5h and 6h. The other higher bits of these ports is set by W83697HF itself. The general decoded address is set to port 295h and port 296h. These two ports are described as following: Port 295h: Index port. Port 296h: Data port. The register structure is showed as the Figure 9.1

6.3 Analog Inputs
The maximum input voltage of the analog pin is 4.096V because the 8-bit ADC has a 16mv LSB. Really, the application of the PC monitoring would most often be connected to power suppliers. The CPU V-core voltage ,+3.3V ,battery and 5VSB voltage can directly connected to these analog inputs. The +12V,-12V and -5V voltage inputs should be reduced a factor with external resistors so as to obtain the input range. As Figure 9.2 shows.

6.3.1
Monitor over 4.096V voltage:
The input voltage +12VIN can be expressed as following equation.
12VIN = V1 x
R2 R1 + R2
The value of R1 and R2 can be selected to 28K Ohms and 10K Ohms, respectively, when the input voltage V1 is 12V. The node voltage of +12VIN can be subject to less than 4.096V for the maximun input range of the 8-bit ADC. The Pin 97 is connected to the power supply VCC with +5V. There are two functions in this pin with 5V. The first function is to supply internal analog power in the W83697HF and the second function is that this voltage with 5V is connected to internal serial resistors to monitor the +5V voltage. The value of two serial resistors are 34K ohms and 50K ohms so that input voltage to ADC is 2.98V which is less than 4.096V of ADC maximum input voltage. The express equation can represent as follows.
Vin = VCC x
50 K 2.98V 50 K + 34 K
where VCC is set to 5V. The Pin 61 is connected to 5VSB voltage. W83697HF monitors this voltage and the internal two serial resistors are 17K and 33K so that input voltage to ADC is 3.3V which less than 4.096V of ADC maximum input voltage.
6.3.2
Monitor negative voltage:
The negative voltage should be connected two series resistors and a positive voltage VREF (is equal to 3.6V). In the Figure 9.2, the voltage V2 and V3 are two negative voltage which they are -12V and 5V respectively. The voltage V2 is connected to two serial resistors then is connected to another terminal VREF which is positive voltage. So as that the voltage node N12VIN can be obtain a posedge voltage if the scales of the two serial resirtors are carefully selected. It is recommanded from Winbond that the scale of two serial resistors are R3=232K ohms and R4=56K ohm. The input voltage of node N12VIN can be calculated by following equation.
N 12VIN = (VREF + V2 ) x (
232 K ) + V2 232 K + 56 K
where VREF is equal 3.6V. If the V2 is equal to -12V then the voltage is equal to 0.567V and the converted hexdecimal data is set to 35h by the 8-bit ADC with 16mV-LSB.This monitored value should be converted to the real negative votage and the express equation is shown as follows.
V2 =
N 12VIN - VREF x 1-
Where is 232K/(232K+56K). If the N2VIN is 0.567 then the V2 is approximately equal to -12V.

W83697HF/ HG
The another negative voltage input V3 (approximate -5V) also can be evaluated by the similar method and the serial resistors can be selected with R5=120K ohms and R6=56K ohms by the Winbond recommended. The expression equation of V3 With -5V voltage is shown as follows.
V3 =
N 5VIN - VREF x 1-
Where the is set to 120K/(120K+56K). If the monitored ADC value in the N5VIN channel is 0.8635, VREF=3.6V and the parameter is 0.6818 then the negative voltage of V3 can be evalated to be -5V.
6.3.3
Temperature Measurement Machine
The temperature data format is 8-bit two's-complement for sensor 2 and 9-bit two's-complement for sensor 1. The 8-bit temperature data can be obtained by reading the CR[27h]. The 9-bit temperature data can be obtained by reading the 8 MSBs from the Bank1 CR[50h] and the LSB from the Bank1 CR[51h] bit 7. The format of the temperature data is show in Table 1.

6.3.3.1. Monitor temperature from thermistor: The W83697HF can connect three thermistors to measure three different envirment temperature. The specification of thermistor should be considered to (1) value is 3435K, (2) resistor value is 10K ohms at 25C. In the Figure 9.2, the themistor is connected by a serial resistor with 10K Ohms, then connect to VREF (Pin 101). 6.3.3.2. Monitor temperature from Pentium IITM thermal diode or bipolar transistor 2N3904 The W83697HF can alternate the thermistor to Pentium IITM (Deschutes) thermal diode interface or transistor 2N3904 and the circuit connection is shown as Figure 9.3. The pin of Pentium IITM D- is connected to power supply ground (GND) and the pin D+ is connected to pin VTINx in the W83697HF. The resistor R=30K ohms should be connected to VREF to supply the diode bias current and the bypass capacitor C=3300pF should be added to filter the high frequency noise. The transistor 2N3904 should be connected to a form with a diode, that is, the Base (B) and Collector (C) in the 2N3904 should be tied togeter to act as a thermal diode. - 24 -

6.4 FAN Speed Count and FAN Speed Control
6.4.1 Fan speed count
Inputs are provides for signals from fans equipped with tachometer outputs. The level of these signals should be set to TTL level, and maximum input voltage can not be over +5.5V. If the input signals from the tachometer outputs are over the VCC, the external trimming circuit should be added to reduce the voltage to obtain the input specification. The normal circuit and trimming circuits are shown as Figure 9.4. Determine the fan counter according to:
Count = 1.35 x 10 6 RPM x Divisor
In other words, the fan speed counter has been read from register CR28 or CR29 or CR2A, the fan speed can be evaluated by the following equation.
1.35 x 10 6 RPM = Count x Divisor
The default divisor is 2 and defined at CR47.bit7~4, CR4B.bit7~6, and Bank0 CR5D.bit5~7 which are three bits for divisor. That provides very low speed fan counter such as power supply fan. The followed table is an example for the relation of divisor, PRM, and count.

The W83697HF temperature sensor 1 SMI# interrupt has two modes:
(1) Comparator Interrupt Mode Setting the THYST (Temperature Hysteresis) limit to 127C will set temperature sensor 1 SMI# to the Comparator Interrupt Mode. Temperature exceeds TO (Over Temperature) Limit causes an interrupt and this interrupt will be reset by reading all the Interrupt Status Register. Once an interrupt event has occurred by exceeding TO, then reset, if the temperature remains above the TO , the interrupt will occur again when the next conversion has completed. If an interrupt event has occurred by exceeding TO and not reset, the interrupts will not occur again. The interrupts will continue to occur in this manner until the temperature goes below TO. (Figure 9.8 ) (2) Two-Times Interrupt Mode Setting the THYST lower than TO will set temperature sensor 1 SMI# to the Two-Times Interrupt Mode. Temperature exceeding TO causes an interrupt and then temperature going below THYST will also cause an interrupt if the previous interrupt has been reset by reading all the interrupt Status Register. Once an interrupt event has occurred by exceeding TO , then reset, if the temperature remains above the THYST , the interrupt will not occur. (Figure 9.9 )

The W83697HF temperature sensor 2 programmed at CR[4Ch] bit 6.
SMI# interrupt has two modes and it is
(1) Comparator Interrupt Mode Temperature exceeding TO causes an interrupt and this interrupt will be reset by reading all the Interrupt Status Register. Once an interrupt event has occurred by exceeding TO, then reset, if the temperature remains above the THYST, the interrupt will occur again when the next conversion has completed. If an interrupt event has occurred by exceeding TO and not reset, the interrupts will not occur again. The interrupts will continue to occur in this manner until the temperature goes below THYST. ( Figure 9.10 ) (2) Two-Times Interrupt Mode Temperature exceeding TO causes an interrupt and then temperature going below THYST will also cause an interrupt if the previous interrupt has been reset by reading all the interrupt Status Register. Once an interrupt event has occurred by exceeding TO , then reset, if the temperature remains above the THYST , the interrupt will not occur. (Figure 9.11 )

6.6 OVT# interrupt mode
The OVT# signal is only related with temperature sensor 2 (VTIN2 ).
6.6.1 The W83697HF temperature sensor 2 Over-Temperature (OVT#) has the following modes
(1) Comparator Mode : Setting Bank1/2 CR[52h] bit 2 to 0 will set OVT# signal to comparator mode. Temperature exceeding TO causes the OVT# output activated until the temperature is less than THYST. ( Figure 9.12) (2) Interrupt Mode: Setting Bank1/2 CR[52h] bit 2 to 1 will set OVT# signal to interrupt mode. Setting Temperature exceeding TO causes the OVT# output activated indefinitely until reset by reading temperature sensor 2 or sensor 3 registers. Temperature exceeding TO , then OVT# reset, and then temperature going below THYST will also cause the OVT# activated indefinitely until reset by reading temperature sensor2 or sensor 3 registers. Once the OVT# is activated by exceeding TO , then reset, if the temperature remains above THYST , the OVT# will not be activated again.( Figure 9.12)

7. CONFIGURATION REGISTER
7.1 Plug and Play Configuration
The W83697HF uses Compatible PNP protocol to access configuration registers for setting up different types of configurations. In W83697HF, there are eleven Logical Devices (from Logical Device 0 to Logical Device B with the exception of logical device 4 for backward compatibility) which correspond to eleven individual functions: FDC (logical device 0), PRT (logical device 1), UART1 (logical device 2), UART2 (logical device 3), CIR (Consumer IR, logical device 6), GPIO1 (logical device 7), GPIO5(logical device 8),GPIO2 ~GPIO4(logical device 9), ACPI ((logical device A), and Hardware monitor (logical device B). Each Logical Device has its own configuration registers (above CR30). Host can access those registers by writing an appropriate logical device number into logical device select register at CR7.
7.2 Compatible PnP
7.2.1 Extended Function Registers In Compatible PnP, there are two ways to enter Extended Function and read or write the configuration registers. HEFRAS (CR26 bit 6) can be used to select one out of these two methods of entering the Extended Function mode as follows:
HEFRAS ADDRESS AND VALUE
0 1
write 87h to the location 2Eh twice write 87h to the location 4Eh twice
After Power-on reset, the value on RTSA# (pin 49) is latched by HEFRAS of CR26. In Compatible PnP, a specific value (87h) must be written twice to the Extended Functions Enable Register (I/O port address 2Eh or 4Eh). Secondly, an index value (02h, 07h-FFh) must be written to the Extended Functions Index Register (I/O port address 2Eh or 4Eh same as Extended Functions Enable Register) to identify which configuration register is to be accessed. The designer can then access the desired configuration register through the Extended Functions Data Register (I/O port address 2Fh or 4Fh). After programming of the configuration register is finished, an additional value (AAh) should be written to EFERs to exit the Extended Function mode to prevent unintentional access to those configuration
- 62 -
W83697HF/ HG
registers. The designer can also set bit 5 of CR26 (LOCKREG) to high to protect the configuration registers against accidental accesses. The configuration registers can be reset to their default or hardware settings only by a cold reset (pin MR = 1). A warm reset will not affect the configuration registers.
7.2.2
Extended Functions Enable Registers (EFERs)
After a power-on reset, the W83697HF enters the default operating mode. Before the W83697HF enters the extended function mode, a specific value must be programmed into the Extended Function Enable Register (EFER) so that the extended function register can be accessed. The Extended Function Enable Registers are write-only registers. On a PC/AT system, their port addresses are 2Eh or 4Eh (as described in previous section).
7.2.3 Extended Function Index Registers (EFIRs), Extended Function Data Registers(EFDRs)
After the extended function mode is entered, the Extended Function Index Register (EFIR) must be loaded with an index value (02h, 07h-FEh) to access Configuration Register 0 (CR0), Configuration Register 7 (CR07) to Configuration Register FE (CRFE), and so forth through the Extended Function Data Register (EFDR). The EFIRs are write-only registers with port address 2Eh or 4Eh on PC/AT systems; the EFDRs are read/write registers with port address 2Fh or 4Fh on PC/AT systems.
7.3 Configuration Sequence
To program W83697HF configuration registers, the following configuration sequence must be followed: (1). Enter the extended function mode (2). Configure the configuration registers (3). Exit the extended function mode
7.3.1 Enter the extended function mode To place the chip into the extended function mode, two successive wrtites of 0x87 must be applied to Extended Function Enable Registers(EFERs, i.e. 2Eh or 4Eh). 7.3.2 Configurate the configuration registers The chip selects the logical device and activates the desired logical devices through Extended Function Index Register(EFIR) and Extended Function Data Register(EFDR). EFIR is located at the same address as EFER, and EFDR is located at address (EFIR+1). First, write the Logical Device Number (i.e.,0x07) to the EFIR and then write the number of the desired logical device to the EFDR. If accessing the Chip(Global) Control Registers, this step is not required. Secondly, write the address of the desired configuration register within the logical device to the EFIR and then write (or read) the desired configuration register through EFDR. 7.3.3 Exit the extended function mode To exit the extended function mode, one write of 0xAA to EFER is required. Once the chip exits the extended function mode, it is in the normal running mode and is ready to enter the configuration mode.

W83697HF/ HG
7.3.4 Software programming example The following example is written in Intel 8086 assembly language. It assumes that the EFER is located at 2Eh, so EFIR is located at 2Eh and EFDR is located at 2Fh. If HEFRAS (CR26 bit 6) is set, 4Eh can be directly replaced by 4Eh and 2Fh replaced by 4Fh. ;----------------------------------------------------------------------------------; Enter the extended function mode ,interruptible double-write | ;----------------------------------------------------------------------------------MOV DX,2EH MOV AL,87H OUT DX,AL OUT DX,AL ;----------------------------------------------------------------------------; Configurate logical device 1, configuration register CRF0 | ;----------------------------------------------------------------------------MOV DX,2EH MOV AL,07H OUT DX,AL ; point to Logical Device Number Reg.
