Port 2 (P20 to P27)
register P2CR and function register P2FC. Resetting resets all bits of output latch P2 to P1,
control register P2CR and function register P2FC to 0. It also sets port 2 to input mode and
connects a pull-up resistor.
address bus (A0 to A7) or (A16 to A23). To use port 2 as an address bus, write 0 to the
output latches to turn off the programmable pull-up resistors.
Port 2 is an 8-bit general-purpose I/O port. I/O can be set on a bit basis using the control
In addition to functioning as a general-purpose I/O port, port 2 also functions as an
