5 Pin Description
Port 0 is a bit-programmable I/O port which can be
configured as a schmitt-trigger input, a push-pull
output, or an open-drain output.
A pull-up resistor can be specified in 1-bit unit.
The P03-P04 are not in the 8-Pin package.
Port 1 is a bit-programmable I/O port which can be
configured as a schmitt-trigger input, a push-pull
output, or an open-drain output.
A pull-up resistor can be specified in 1-bit unit.
The P10-P17 are not in the 10-Pin/8-Pin package.
The P16-P17 are not in the 16-Pin package.
Port 2 is a bit-programmable I/O port which can be
configured as a schmitt-trigger input, a push-pull
output, or an open-drain output.
A pull-up resistor can be specified in 1-bit unit.
The P20-P21 are not in the 16-Pin/10-Pin/8-Pin
package.
