Section 9 I/O Ports
Port 2 Register (PORT2)
PORT2 is an 8-bit read-only register that shows the pin states. It cannot be written to. Writing of
output data for the port 2 pins (P2
If a port 2 read is performed while P2DDR bits are set to 1, the P2DR values are read. If a port 2
read is performed while P2DDR bits are cleared to 0, the pin states are read.
After a power-on reset and in hardware standby mode, PORT2 contents are determined by the pin
states, as P2DDR and P2DR are initialized. PORT2 retains its prior state after a manual reset, and
in software standby mode.
