Port 4 is a 2-bit I/O port with an output latch. Each bit of this port can be set to the input or output mode by using
Reset signal generation sets port 4 to the input mode.
Figures 4-11 shows the block diagram of port 4.
Note In PD78F920x, set PM41, PM42, and PM44 to PM47 to "0" at program initialization.
The ports are controlled by the following four types of registers.
Port mode registers (PM2 to PM4)
Port registers (P2 to P4)
Port mode control register 2 (PMC2) (
Pull-up resistor option registers (PU2 to PU4)
