I/O Bi-direction I/O port
Software controlled pull-high for all pins
I/O Bi-direction I/O port with system wake-up function
Software controlled pull-high for all pins
I/O Bi-direction I/O pins with driving ability selection
I/O Bi-direction I/O pin
By connecting IOC4 and IOC6 together
IOC4 is a bi-direction I/O pin with system wake-up and software controlled pull-high function
IOC6 is a bi-direction I/O pin with software controlled open-drain output
Note : Both IOC4 and IOC6 should not be defined as output pins at the same time.
By connecting IOC5 and IOC7 together
IOC5 is a bi-direction I/O pin with system wake-up and software controlled pull-high function
IOC7 is a bi-direction I/O pin with software controlled open-drain output
Note : Both IOC5 and IOC7 should not be defined as output pins at the same time.
