8-Bit Microcontroller
IC Product Specification (V1.2) 03.12.2020
 65
(This specification is subject to change without prior notice)
6.3 I/O Ports
The I/O registers, Port 5~Port 7 are bidirectional tri-state I/O ports. All can be pulled high
and pulled low internally by software. Furthermore, they can also be set as open-drain
output and high sink/drive by software. Ports 5~7 features wake-up and interrupt function
as well as input status change interrupt function. Each I/O pin can be defined as "input" or
"output" pin by the I/O control register (IOC5 ~ IOC7).
The I/O registers and I/O control registers are both readable and writable. The I/O
interface circuits for Port 5 ~ Port 7 are shown in the following Figures 6-4a to 6-4d.
