11 / 285 page Pin Description Mitsubishi microcomputers M16C / 6K7 Group SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER 10 Rev.1.0 Pin Description Signal name I/O port P6 I/O port P7 I/O port P8 I/O port P85 I/O port P9 I/O port P10 I/O type Input/output Input/output Input/output Input/output Input/output Input Input/output Input/output Function This is an 8-bit I/O port equivalent to P0. (Except that P60 to P63's output type is N channel open drain only; P64 to P67's output type is CMOS 3 state only; P60 to P63 no internal pull-up registor support.) By software selecting, this port can be used for I2C-BUS interface, UART0/UART1 input/ output pin, timerA3,A4 output pin or same frequency with XIN clock output pin. When P60 to P63 used as I2C-BUS interface SDA,SCL, the input level of these pins are CMOS/ SMBUS selectable. This is an 8-bit I/O port equivalent to P0. (Except that P70 to P77 output type is N channel open drain only; no internal pull-up registor support.) By software selecting, this port can be used for external interrupt input pin, timerA0 to A3 and timerB5 input pin, PS2 interface input/output pin, or UART2 input/output pin. P70 to P75 pins' level can be read regardless of the setting of input port or output port. P80 to P84, P86, and P87 are I/O ports with the same functions as P0. (Except that P86 to P87's output type is CMOS 3 state only; P80 to P84's output type is N channel open drain only; P85 is input port only; the P80 to P84 and P85 are no internal pull-up registor support.) By software selecting, this port can be used for timer A4, B0 to B2, I2C-BUS interface I/O pins. P86 and P87 can be set using software to function as the I/O pins for a sub clock generation circuit. In this case, connect a quartz oscillator between P86 (XCOUT pin) and P87 (XCIN pin). P85 is an input-only port that ______ ______ also functions for NMI. The NMI interrupt is generated when ______ the input at this pin changes from “H” to “L”. The NMI function cannot be cancelled using software. This is an 8-bit I/O port equivalent to P0. (Except that output type is CMOS 3 state only.) By software selecting, the port can be used for external interrupt, timer B3 to B4, A-D converter extended input pins, A-D trigger, SI/O3, SI/O4 I/O pins, PWM, D-A converter output pins. This is an 8-bit I/O port equivalent to P0. (Except that output type is CMOS 3 state only.) By software selecting, the port can be used for A-D converter, external interrupt input pins. Pin name P60 to P67 P70 to P77 P80 to P84, P86, P87, P85 P90 to P97 P100 to P107 |
