or output. The control register P2CR and function register P2FC are used to set the port for input or
output. A reset sets all bits of output latch P2 to 1 and clears all bits of P2CR and P2FC to 0, putting port

Port 2 is an 8-bit general-purpose input/output port whose bits can each be set independently for input
In addition to functioning as a general-purpose input/output port, this port can function as an address
