Input/Output
ports
M34552M4H/M8H/G8H
D0–D5 ^I/O
Six independent I/O ports.
Input is examined by skip decision.
The output structure can be switched by software.
Port D5 is also used as INT pin.
D6, D7 ^Output
Two independent output ports.
Ports D6 and D7 are also used as XCIN and XCOUT, respectively.
P00–P03 ^I/O
4-bit I/O port; A pull-up function, a key-on wakeup function and output structure can be switched
by software. Ports P00–P03 are also used as SEG21–SEG24, respectively.
P10–P13 ^I/O
4-bit I/O port; A pull-up function, a key-on wakeup function and output structure can be switched
by software. Ports P10–P13 are also used as SEG25–SEG28, respectively.
P20–P23 ^I/O
4-bit I/O port; The output structure can be switched by software. Ports P20–P23 are also used
as SEG17–SEG20, respectively.
C
Output
1-bit output; Port C is also used as CNTR pin.
