SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Pin Description
Pin name
P70 to P77
Signal name
I/O port P7
I/O type
Function
Input/output
This is an 8-bit I/O port equivalent to P3. This is CMOS input/output.
When set for input, the user can specify in units of four bits by software
whether or not they are tied to a pull-up resistor. P70 to P72 function as
TimerB0 to B2 input pins as selected by software. P73 function as
TimerA0 I/O pin as selected by software. P74 to P77 function as
TimerA1 to A4 I/O pins, and UART1 I/O pins as selected by software.
P80 to P87
I/O port P8
Input/output
This is an 8-bit I/O port equivalent to P7. When set for input, the user
can specify in units of four bits by software whether or not they are tied
to a pull-up resistor. P80 to P85 function as external interrupt input pins
as selected by software. P86,P87 function as sub-clock input pin as
selected by software. In this case, connect a quarts oscillator between
P86(XOUT pin) and P87(XCIN pin)
P90 to P97 I/O port P9
Input/output
This is an 8-bit I/O port equivalent to P7. When set for input, the user
can specify in units of four bits by software whether or not they are tied
to a pull-up resistor. P97 function as D-A converter output pins, clock
output pins (same frequency of XIN/8, XIN/32 or XCIN) and DIM signal
output pin of FLD controller as selected by software. P96 function as D-
A converter output pins and clock I/O pin of serial I/O with automatic
transfer as selected by software. P90 to P95 function as I/O pin of serial
I/O with automatic transfer as selected by software.
P100 to P107 I/O port P10
Input/output
This is an 8-bit I/O port equivalent to P7. When set for input, the user
can specify in units of four bits by software whether or not they are tied
to a pull-up resistor. Pins in this port also function as A-D converter
input pins as selected by software.
Note 1: Supply 4.0V to 5.5V to the VCC pin in flash memory version.
