I/O
8-bit I/O ports in CMOS, having a direction register to select an input or
output.
Each pin is set as an input port or output port. An input port can be set for a
pull-up or for no pull-up in 4-bit unit by program.
I/O
VCC1
I/O ports having equivalent functions to P0.
P9_2 to P9_7
P4_0 to P4_3,
P7_0, P7_1,
P7_6, P7_7
P8_5
I/O
I
VCC1
VCC1
I/O ports having equivalent functions to P0.
(except P7_0 and P7_1 for the N-channel open drain output.)
Input port
Input pin for the _N__M___I_ interrupt.
Pin states can be read by the P8_5 bit in the P8 register.
I : Input
O : Output
I/O : Input and output
NOTES:
1. There is no external connections for port P1, P4_4 to P4_7, P7_2 to P7_5 and P9_1 in 80-pin version.
Set the direction bits in these ports to “1” (input mode), and set the output data to “0” (“L”) using the program.
