CHAPTER 4 PORT FUNCTIONS

4.2.1
Port 2
Port 2 is a 4-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 2 (PM2). When the P20 to P23 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 2 (PU2).
This port is also used as the analog input pins of the internal A/D converter.
Reset signal generation sets port 2 to the input mode.
Figure 4-2 shows the block diagram of port 2.
