1. DIFFERENCES AMONG MODELS IN PD784216A, 784216AY/784218A, 784218AY SUBSERIES
The only difference among the PD784214A, 784215A, 784216A, 784217A, and 784218A lies in the internal memory capacity. The PD784214AY, 784215AY, 784216AY, 784217AY, and 784218AY are models with the addition of an I2C bus control function. The PD78F4216A, 78F4216AY, 78F4218A, and 78F4218AY are provided with a 128 KB/256 KB flash memory instead of the mask ROM of the above models. These differences are summarized in Table 1-1.

Note The internal flash memory capacity and internal RAM capacity can be changed using the internal memory size switching register (IMS). Caution There are differences in noise immunity and noise radiation between the flash memory and mask ROM versions. When pre-producing an application set with the flash memory version and then mass-producing it with the mask ROM version, be sure to conduct sufficient evaluations on the commercial samples (not engineering samples) of the mask ROM version.

6.2 CPU Registers
6.2.1 General-purpose registers Sixteen 8-bit general-purpose registers are available. Two 8-bit registers can also be used in pairs as a 16-bit register. Of the 16-bit registers, four can be used in combination with an 8-bit register for address expansion as 24bit address specification registers. Eight banks of these register sets are available and can be selected by using software or the context switching function. The general-purpose registers except the V, U, T, and W registers for address expansion are mapped to the internal RAM. Figure 6-6. General-Purpose Register Format

6.2.3 Special function registers (SFRs) The special function registers, such as the mode registers and control registers of the internal peripheral hardware, are registers to which special functions are assigned. These registers are mapped to the 256-byte space of addresses 0FF00H to 0FFFFHNote. Note On execution of the LOCATION 0H instruction. FFF00H to FFFFFH on execution of the LOCATION 0FH instruction. Caution Do not access an address in this area to which no SFR is assigned. If such an address is accessed by mistake, the PD784218A may enter a deadlocked state. This deadlock state can be cleared only by inputting the RESET signal. Table 6-1 lists the special function registers (SFRs). The meanings of the symbols in this table are as follows. * Symbol ................................ Symbol indicating an SFR. in the C compiler (CC78K4). * R/W ..................................... Indicates whether the SFR is read-only, write-only, or read/write. R/W: Read/write R: W: Read-only Write-only This symbol is reserved for NEC's assembler
(RA78K4). It can be used as an sfr variable by means of the #pragma sfr command
* Bit units for manipulation ..... Bit units in which the value of the SFR can be manipulated. SFRs that can be manipulated in 16-bit units can be described as the operand sfrp of an instruction. To specify the address of this SFR, describe an even address. SFRs that can be manipulated in 1-bit units can be described as the operand of a bit manipulation instruction. * After reset............................ Indicates the status of the register when the RESET signal has been input.

Caution
When using the main system clock and subsystem clock oscillator, wire as follows in the area enclosed by the broken lines in Figures 7-3 and 7-4 to avoid an adverse effect from wiring capacitance. * Keep the wiring length as short as possible. * Do not cross the wiring with other signal lines. * Do not route the wiring near a signal line through which a high fluctuating current flows. * Always make the ground point of the oscillator capacitor the same potential as VSS. Do not ground the capacitor to a ground pattern through which a high current flows. * Do not fetch signals from the oscillator. Note that the subsystem clock oscillator has a low amplification factor to reduce the current consumption.

7.3 Real-Time Output Port
The real-time output function is to transfer data set in advance to the real-time output buffer register to the output latch as soon as the timer interrupt or external interrupt has occurred in order to output the data to an external device. The pins that output the data to the external device constitute a port called a real-time output port. Because the real-time output port can output signals without jitter, it is ideal for controlling a stepper motor. Figure 7-5. Block Diagram of Real-Time Output Port

7.5 A/D Converter
An A/D converter converts an analog signal input into a digital signal. This microcontroller is provided with an A/D converter with a resolution of 8 bits and eight channels (ANI0 to ANI7). This A/D converter is of successive approximation type and the result of conversion is stored in an 8-bit A/D conversion result register (ADCR). The A/D converter can be started in the following two ways: * Hardware start Conversion is started by trigger input (P03). * Software start Conversion is started by setting the A/D converter mode register (ADM). One analog input channel is selected from ANI0 to ANI7 for A/D conversion. When A/D conversion is started by means of hardware start, conversion is stopped after it has been completed. When conversion is started by means of software start, A/D conversion is repeatedly executed. Each time conversion has been completed, an interrupt request (INTAD) is generated. Figure 7-7.

7.6 D/A Converter
A D/A converter converts a digital signal input into an analog signal. This microcontroller is provided with a voltage output type D/A converter with a resolution of 8 bits and two channels. The conversion method is of R-2R resistor ladder type. D/A conversion is started by setting DACE0 of D/A converter mode register 0 (DAM0) and DACE1 of D/A converter mode register 1 (DAM1). The D/A converter operates in the following two modes: * Normal mode The converter outputs an analog voltage immediately after it has completed D/A conversion. * Real-time output mode The converter outputs an analog voltage in synchronization with an output trigger after it has completed D/A conversion.

7.7.1 Asynchronous serial interface/3-wire serial I/O (UART/IOE) Two channels of serial interfaces for which an asynchronous serial interface mode and a 3-wire serial I/O mode can be selected are provided. (1) Asynchronous serial interface mode In this mode, data of 1 byte following the start bit is transmitted or received. Because an on-chip baud rate generator is provided, a wide range of baud rates can be set. Moreover, the clock input to the ASCK pin can be divided to define a baud rate. When the baud rate generator is used, a baud rate conforming to the MIDI standard (31.25 kbps) can also be obtained. Figure 7-10. Block Diagram in Asynchronous Serial Interface Mode

7.10 Edge Detection Function
The interrupt input pins (INTP0, INTP1, NMI/INTP2, INTP3 to INTP6) are used not only to input interrupt requests but also to input trigger signals to the internal hardware units. Because these pins operate at an edge of the input signal, they have a function to detect an edge. Moreover, a noise elimination function is also provided to prevent erroneous detection due to noise.

7.12 Watchdog Timer
A watchdog timer is provided to detect a CPU runaway. This watchdog timer generates a non-maskable or maskable interrupt unless it is cleared by software within a specified interval time. Once enabled to operate, the watchdog timer cannot be stopped by software. Whether the interrupt by the watchdog timer or the interrupt input from the NMI pin takes precedence can be specified.

8.1 Interrupt Sources
Table 8-2 shows the interrupt sources available. As shown, interrupts are generated by 29 types of sources, execution of the BRK instruction, BRKCS instruction, or an operand error. The priority of interrupt servicing can be set to four levels, so that nesting can be controlled during interrupt servicing and so that which of the two or more interrupts that simultaneously occur should be serviced first can be determined. When the macro service function is used, however, nesting always proceeds. The default priority is the priority (fixed) of the service that is performed if two or more interrupt requests, having the same priority, are simultaneously generated (refer to Table 8-2). Table 8-2. Interrupt Sources (1/2)

8.2 Vectored Interrupt
Execution branches to a servicing routine by using the memory contents of a vector table address corresponding to the interrupt source as the address of the branch destination. So that the CPU performs interrupt servicing, the following operations are performed: * On branching: Saves the status of the CPU (contents of PC and PSW) to stack * On returning: Restores the status of the CPU (contents of PC and PSW) from stack
To return to the main routine from an interrupt service routine, the RETI instruction is used. The branch destination address is in a range of 0 to FFFFH. Table 8-3. Vector Table Address

8.3 Context Switching
When an interrupt request is generated or when the BRKCS instruction is executed, a predetermined register bank is selected by hardware. Context switching is a function that branches execution to a vector address stored in advance in the register bank, while at the same time stacking the current contents of the program counter (PC) and program status word (PSW) to the register bank. The branch address is in a range of 0 to FFFFH. Figure 8-1. Context Switching Operation When Interrupt Request Is Generated

8.4 Macro Service
This function is to transfer data between memory and a special function register (SFR) without intervention by the CPU. A macro service controller accesses the memory and SFR in the same transfer cycle and directly transfers data without loading it. Because this function does not save or restore the status of the CPU, or load data, data can be transferred at high speeds. Figure 8-2. Macro Service

Each time macro service requests INTST1 and INTST2 are generated, the next transmit data is transferred from memory to TXS1 and TXS2. When data n (last byte) has been transferred to TXS1 and TXS2 (when the transmit data storage buffer has become empty), vectored interrupt requests INTST1 and INTST2 are generated.

9.1 Memory Expansion
External program memory and data memory can be connected in two stages: 256 KB and 1 MB. To connect the external memory, ports 4 through 6 and port 8 are used. The external memory can be connected in the following two modes: * Multiplexed bus mode: The external memory is connected by using a time-division address/data bus. The number of ports used when the external memory is connected can be reduced in this mode. * Separate bus mode: The external memory is connected by using an address bus and data bus independent of each other. Because an external latch circuit is not necessary, this mode is useful for reducing the number of components and mounting area on the printed wiring board.
9.2 Programmable Wait
Wait state(s) can be inserted to the memory space (00000H to FFFFFH) while the RD and WR signals are active. In addition, there is an address wait function that extends the active period of the ASTB signal to gain the address decode time.

10. STANDBY FUNCTION
This function is to reduce the power consumption of the chip, and can be used in the following modes: * HALT mode: Stops supply of the operating clock to the CPU. This mode is used in combination with the normal operation mode for intermittent operation to reduce the average power consumption. * IDLE mode: Stops the entire system except for the oscillator, which continues operating. The power consumption in this mode is close to that in the STOP mode. However, the time required to restore the normal program operation from this mode is almost the same as that from the HALT mode. * STOP mode: Stops the main system clock and thereby stops all the internal operations of the chip. * Low power consumption mode: Consequently, the power consumption is minimized with only leakage current flowing. The main system clock is stopped and the subsystem clock is used as the system clock. The CPU can operate on the subsystem clock to reduce the current consumption. * Low power consumption HALT mode: This is a standby function in the low power consumption mode and stops the operation clock of the CPU, to reduce the power consumption of the entire system. * Low power consumption IDLE mode: This is a standby function in the low power consumption mode and stops the entire system except the oscillator, to reduce the power consumption of the entire system. These modes are programmable. The macro service can be started from the HALT mode or low power consumption HALT mode. After macro service processing is executed, the system returns to the HALT mode again. The transition of the standby status is shown in Figure 10-1.

11. RESET FUNCTION
When a low-level signal is input to the RESET pin, the system is reset, and each hardware unit is initialized (reset). During the reset period, oscillation of the main system clock is unconditionally stopped. Consequently, the current consumption of the entire system can be reduced. When the RESET signal goes high, the reset status is cleared. And after the oscillation stabilization time (84.0 ms at 12.5 MHz operation) elapses, the contents of the reset vector table are set to the program counter (PC), execution branches to an address set to the PC, and program execution is started from that branch address. Therefore, the program can be reset and started from any address. Figure 11-1. Oscillation of Main System Clock During Reset Period

Caution
Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any parameter. That is, the absolute maximum ratings are rated values at which the product is on the verge of suffering physical damage, and therefore the product must be used under conditions that ensure that the absolute maximum ratings are not exceeded.

Cautions 1. When using the main system clock oscillator, wire as follows in the area enclosed by the broken lines in the above figures to avoid an adverse effect from wiring capacitance. * Keep the wiring length as short as possible. * Do not cross the wiring with other signal lines. * Do not route the wiring near a signal line through which a high fluctuating current flows. * Always make the ground point of the oscillator capacitor the same potential as VSS. * Do not ground the capacitor to a ground pattern through which a high current flows. * Do not fetch signals from the oscillator. 2. When the main system clock is stopped and the system is operated by the subsystem clock, the subsystem clock should be switched back to the main system clock after the oscillation stabilization time is secured by the program. Remark For the resonator selection and oscillator constant, users are required to either evaluate the oscillation themselves or apply to the resonator manufacturer for evaluation.

Note Time required to stabilize oscillation after applying supply voltage (VDD). Cautions 1. When using the subsystem clock oscillator, wire as follows in the area enclosed by the broken lines in the above figures to avoid an adverse effect from wiring capacitance. * Keep the wiring length as short as possible. * Do not cross the wiring with other signal lines. * Do not route the wiring near a signal line through which a high fluctuating current flows. * Always make the ground point of the oscillator capacitor the same potential as VSS. * Do not ground the capacitor to a ground pattern through which a high current flows. * Do not fetch signals from the oscillator. 2.

Notes 1. For the start condition, the first clock pulse is generated after the hold time. 2. To fill the undefined area of the SCL0 falling edge, it is necessary for the device to provide an internal SDA0 signal (on VIHmin.) with at least 300 ns of hold time. 3. If the device does not extend the SCL0 signal low-level hold time (tLOW), only the maximum data hold time tHD : DAT needs to be satisfied. 4. The high-speed mode I2C bus can be used in a standard mode I2C bus system. In this case, the conditions described below must be satisfied. * If the device does not extend the SCL0 signal low-level hold time tSU : DAT 250 ns * If the device extends the SCL0 signal low-level hold time Be sure to transmit the data bit to the SDA0 line before the SCL0 line is released (tRmax. + tSU : = 1,000 + 250 = 1,250 ns by standard mode I2C bus specification) 5.

NOTES FOR CMOS DEVICES
1 PRECAUTION AGAINST ESD FOR SEMICONDUCTORS Note: Strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and ultimately degrade the device operation. Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it once, when it has occurred. Environmental control must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using insulators that easily build static electricity. Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work bench and floor should be grounded. The operator should be grounded using wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for PW boards with semiconductor devices on it. 2 HANDLING OF UNUSED INPUT PINS FOR CMOS Note: No connection for CMOS device inputs can be cause of malfunction. If no connection is provided to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected to VDD or GND with a resistor, if it is considered to have a possibility of being an output pin. All handling related to the unused pins must be judged device by device and related specifications governing the devices. 3 STATUS BEFORE INITIALIZATION OF MOS DEVICES Note: Power-on does not necessarily define initial status of MOS device. Production process of MOS does not define the initial operation status of the device. Immediately after the power source is turned ON, the devices with reset function have not yet been initialized. Hence, power-on does not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the reset signal is received. Reset operation must be executed immediately after power-on for devices having reset function.
