5.4 I/O Ports

The I/O registers, Port 5 ~ Port 9, are bidirectional tri-state I/O ports. Port 7 can be

pulled-high internally by software control. In addition, P66 and P67 can also have

open-drain outputs through software control. Wake-up functions are available from

P96 and P97. Each I/O pin can be defined as an "input" or "output" pin by the I/O

control registers (IOC5 ~ IOC9). The I/O registers and I/O control registers are both

readable and writable. The I/O interface circuits for Port 5 ~ Port 9 are shown in Figure

5-8.
