6 / 115 page  5 MITSUBISHI MICROCOMPUTERS M37754M8C-XXXGP, M37754M8C-XXXHP M37754S4CGP, M37754S4CHP PRELIMINAR Y Notice: This is not a final specification. Some parametric limits are subject to change. SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER PIN DESCRIPTION (MICROCOMPUTER MODE) Functions Input Input Input Output Output Input Input I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O Input/ Output Name Pin VCC, VSS CNVSS RESET XIN XOUT E BYTE (Note) AVCC, AVSS VREF P00 – P07 P10 – P17 P20 – P23, P27 P30 – P33 P40 – P47 P50 – P57 P60 – P67 P70 – P77 P80 – P87 P90 – P95 Supply 5 V±10 % to VCC and 0 V to VSS. This pin controls the processor mode. Connect to VSS for single-chip mode or memory expansion mode. Connect to VCC for microprocessor mode and external ROM version. This is reset input pin. The microcomputer is reset when supplying “L” level to this pin. These are I/O pins of internal clock generating circuit. Connect a ceramic or quartz- crystal resonator between XIN and XOUT. 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 outputs enable signal E, which indicates access state of data bus for single-chip mode. ___ This pin outputs RD signal for memory expansion mode or microprocessor mode. This pin determines whether the external data bus is 8-bit width or 16-bit width for memory expansion mode or microprocessor mode. The width is 16 bits when “L” signal inputs and 8 bits when “H” signal inputs. Power supply for the A-D converter and the D-A converter. Connect AVCC to VCC and AVSS to VSS externally. This is reference voltage input pin for the A-D converter and the D-A converter. In single-chip mode, port P0 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 ports are in the input mode when reset. Address (A0 - A7) is output in memory expansion mode or microprocessor mode. In single-chip mode, these pins have the same functions as port P0. Address (A8 - A15) is output in memory expansion mode or microprocessor mode. In single-chip mode, these pins have the same functions as port P0. Address (A16 - A19, A23) is output in memory expansion mode or microprocessor mode. In single-chip mode, these pins have the same functions as port P0. In memory ___ ____ _____ expansion mode or microprocessor mode, WR, BHE , ALE, and HLDA signals are output. In single-chip mode, these pins have the same functions as port P0. In memory _____ expansion mode or micro processor mode, P40, P41, and P42 become HOLD and ____ RDY input pins, and clock φ1 output pin respectively. Functions of other pins are the same as in single-chip mode. In memory expansion mode, P42 can be programmed as I/O port. In addition to having the same functions as port P0 in single-chip mode, these pins also function as I/O pins for timer A0, timer A1, timer A2, timer A3, output pins for motor drive waveform, and input pins for key input interrupt. In addition to having the same functions as port P0 in single-chip mode, these pins ____ also function as I/O pins for timer A4, input pins for external interrupt input INT0, ____ ____ INT1, and INT2, and input pins for timer B0, timer B1, and timer B2. In addition to having the same functions as port P0 in single-chip mode, these pins also function as input pins for A-D converter. In addition to having the same functions as port P0 in single-chip mode, these pins also function as I/O pins for UART0, UART1, output pins for D-A converter, and ____ input pin for INT4. In addition to having the same functions as port P0 in single-chip mode, these pins ____ also function as input pin for INT3, output pins for motor drive waveform. In memory expansion mode and microprocessor mode, these pins can be ___ ___ programmed as address (A20 - A22) or output pins for CS0 – CS4 Power supply CNVSS input Reset input Clock input Clock output Enable output Bus width select input Analog supply input Reference voltage input I/O port P0 I/O port P1 I/O port P2 I/O port P3 I/O port P4 I/O port P5 I/O port P6 I/O port P7 I/O port P8 I/O port P9 Note: It is impossible to change the input level of the BYTE pin in each bus cycle. In other words, bus width cannot be switched dynamically. Fix the input level of the BYTE pin to “H” or “L” according to the bus width used. |
