W83697UF/W83697UG
1. GENERAL DESCRIPTION
The W83697UF 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 W83697UF'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 W83697UF 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 W83697UF greatly reduces the number of components required for interfacing with floppy disk drives. The W83697UF supports four 360K, 720K, 1.2M, 1.44M, or 2.88M disk drives and data tranufer rates of 250 Kb/s, 300 Kb/s, 500 Kb/s,1 Mb/s, and 2 Mb/s. The W83697UF provides four 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. All 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 W83697UF 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 W83697UF 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 95/98TM, which makes system resource allocation more efficient than ever. The W83697UF 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 W83697UF is made to fully comply with Microsoft PC98 and PC99 Hardware Design Guide, and meet the requirements of ACPI. The W83697UF 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 W83697UF provides Flash ROM interface. That can support up to 4M legacy flash ROM.

6. CONFIGURATION REGISTER
6.1 Plug and Play Configuration
The W83697UF uses Compatible PNP protocol to access configuration registers for setting up different types of configurations. In W83697UF, 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.

6.2 Compatible PnP
6.2.1 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 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.
6.2.2
Extended Functions Enable Registers (EFERs)
After a power-on reset, the W83697UF enters the default operating mode. Before the W83697UF 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).
6.2.3
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.
6.3 Configuration Sequence
To program W83697UF 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

W83697UF/W83697UG
6.3.1 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).
6.3.2
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.
6.3.3
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.
6.3.4
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 OUT OUT DX,2EH DX,AL DX,AL MOV AL,87H |
