CHAPTER 4 PORT FUNCTIONS
User’s Manual U18172EJ3V0UD

4.2.3
Port 4
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
port mode register 4 (PM4)
Note. When the P40 and P43 pins are used as an input port, an on-chip pull-up resistor can
be connected in 1-bit units by using pull-up resistor option register 4 (PU4).
Reset signal generation sets port 4 to the input mode.
Figures 4-11 shows the block diagram of port 4.
Note In
μPD78F920x, set PM41, PM42, and PM44 to PM47 to "0" at program initialization.

Registers Controlling Port Functions
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) (μPD78F920x only)
Pull-up resistor option registers (PU2 to PU4)
