PIN DESCRIPTION (MICROCOMPUTER MODE)
Pin Vcc, Vss MD0 MD1 RESET XIN XOUT BYTE Name Power supply input MD0 MD1 Reset input Clock input Clock output External data bus width select input Input/ Output -- Input Input Input Input Output Functions Apply 5 V0.5 V to Vcc, and 0 V to Vss. Connect this pin to VCC. Connect this pin to Vss. The microcomputer is reset when VSS-level voltage is applied to this pin. These are input and output pins of the internal clock generating circuit. Connect a ceramic or quartz- crystal resonator between the XIN and XOUT pins. When an external clock is used, the clock source should be connected to the XIN pin, and the XOUT pin should be left open. This pin determines whether the external data bus has an 8-bit width or 16-bit width for the memory expansion mode or microprocessor mode. The width is 16 bits when VSS-level voltage is input, and 8 bits when VCC-level voltage is applied. When BYTE = Vss level, by the register setting, the external data bus for each of areas CS1 to CS3 can have a width of 8 bits. This pin determines the XIN-input-clock division select bit's (Note) state at reset and the input level at pin XIN. Power supply input pins for the A-D converter and the D-A converter. Connect AVcc to Vcc, and AVss to Vss externally. This is the reference voltage input pin for the A-D converter and the D-A converter. Address (A16-A23) is output. These pins also function as I/O port pins according to the register setting. The low-order 8 bits of data (D0-D7) are input/output. When the external data bus has an 8-bit width, address (LA0-LA7) output and data (D0-D7) input/output can be performed with the time-sharing method, according to the register setting. s When 8-bit external data bus is used Port P2 is an 8-bit I/O port. This port has an I/O direction register, and each pin can be programmed for input or output. These pins enter the input mode at reset. s When 16-bit external data bus is used The high-order 8 bits of data (D8-D15) are input or output. P30 functions as an input pin of RDY; and P31,P32, P33 function as the output pins of RD, BLW, BHW, respectively. P30 also functions as an I/O port pin according to the register setting. When the external data bus has a width of 8 bits, the BHW pin functions as an I/O port pin (P33). P40-P44 function as output or input pins of ALE, 1, HLDA, HOLD, CS0, and P45-P47 as I/O port pins, respectively. According to the register setting, P40-P43 also function as I/O port pins, and P45-P47 as output pins of CS1-CS3. Port P5 is an 8-bit I/O port. This port has an I/O direction register, and each pin can be programmed for input or output. These pins enter the input mode at reset. These pins also function as I/O pins for timers A0-A3, output pins for the real-time output, and input pins for the key-input interrupt. Port P6 is an 8-bit I/O port. This port has an I/O direction register, and each pin can be programmed for input or output. These pins enter the input mode at reset. These pins also function as I/O pins for timer A4, input pins for external interrupt inputs INT0-INT2, and input pins for timers B0-B2. Port P7 is an 8-bit I/O port. This port has an I/O direction register, and each pin can be programmed for input or output. These pins enter the input mode at reset. These pins also function as input pins for the A-D converter, output pins for the D-A converter, and input pins for INT2, INT3, and INT4. Port P8 is an 8-bit I/O port. This port has an I/O direction register, and each pin can be programmed for input or output. These pins enter the input mode at reset. These pins also function as I/O pins for UART0, UART1, and input pins for INT3 and INT4. Address (A0-A7) is output. Address (A8-A15) is output. Also, these pins function as I/O port pins according to the register setting. This pin is for a non-maskable interrupt.

BASIC FUNCTION BLOCKS
The M37903S4CHP has the same function as that of the M37903F8CHP except for the following. Therefore, refer to the datasheet of the M37903F8CHP. * The memory allocation of the M37903S4CHP differs from that of the M37903F8CHP. * The M37903S4CHP operates only in the microprocessor mode.
MEMORY
Figure 1 shows the memory map. The address space is 16 Mbytes from addresses 016 to FFFFFF16. The address space is divided into
64-Kbyte units called banks. The banks are numbered from 016 to FF16. Bank FF16 is a reserved area for the development support tool. Therefore, do not use bank FF16. Internal RAM is assigned as shown in Figure 1. Addresses FFC016 to FFFF16 contain the RESET and the interrupt vector addresses, and the interrupt vectors are stored there. For these addresses, use the ROM. For details, refer to the section on interrupts. Assigned to addresses 016 to FF16 are peripheral devices such as I/O ports, A-D converter, D-A converter, UART, timers, interrupt control registers, etc. Figures 2 and 3 show the location of SFRs.
