Pull-high
or None
Bidirectional 8-bit input/output port. Software* instructions de-
terminetheCMOSoutputorschmitttriggerinputwithorwithout
pull-high resistor.
PC0
I/O
Wake-up
Pull-high
or None
This pin is an I/O port. NMOS open drain output with pull-high
resistor and can be used as DATA or CLOCK line of PS2. This pin
can be configured as a wake-up input by ROM code option.
PC1
I/O
Wake-up
Pull-high
or None
This pin is an I/O port. NMOS open drain output with pull-high
resistor and can be used as DATA or CLOCK line of PS2. This pin
can be configured as a wake-up input by ROM code option.
