Pin Description
Pin Name I/O
Mask
Option
Description
Wake-up Bidirectional 8-bit input/output port. Each bit can be configured as a wake-up input
PA0~PA7 I/O Pull-high by mask option. Software* instructions determine the CMOS output or Schmitt
or None Trigger input with or without 12K pull-high resistor.
PB0~PB7
I/O
Pull-high Bidirectional 8-bit input/output port. Software* instructions determine the output or
or None Schmitt Trigger input with or without pull-high resistor.
Wake-up This pin is an I/O port. NMOS open drain output with pull-high resistor and can be
PC0
I/O Pull-high used as DATA or CLOCK line of PS2. This pin can be configured as a wake-up
or None input by mask option.
Wake-up This pin is an I/O port. NMOS open drain output with pull-high resistor and can be
PC1
I/O Pull-high used as DATA or CLOCK line of PS2. This pin can be configured as a wake-up
or None input by mask option.
Bidirectional 2-bit input/output port. Each bit can be configured as a wake-up input
Wake-up by mask option. Software* instructions determine the CMOS output or Schmitt
PC2~PC3 I/O Pull-high Trigger input with or without pull-high resistor.
or None PC2 also as external interrupt input pin. PE0 determine whether rising edge or
falling edge of PC2 to trigger the INT circuit.
PC4~PC7
I/O
Pull-high Bidirectional 4-bit input/output port. Software* instructions determine the CMOS
or None output or Schmitt Trigger input with or without pull-high resistor.
PD0~PD7
I/O
Pull-high Bidirectional 8-bit input/output port. Software* instructions determine the CMOS
or None output or Schmitt Trigger input with or without pull-high resistor.
