3.3 Digital I/O Configuration
The 32-channel high-speed digital I/O lines are bi-direction and
divided into four groups. Each group contains 8 channels and can
be configured as input port or output port individually. At power-up
status, all the I/O lines are preset to input ports. When configuring
to digital output mode, the initial status of digital outputs are in tri-
state. The possible configuration modes are as follows:
Port Channel Power-up status Direction
Port A D0 ~ D7 Input Input or output
Port B D8 ~ D15 Input Input or output
Port C D16 ~ D23 Input Input or output
Port D D24 ~ D31 Input Input or output
