P1, P2, and P3 are the SFR latches of ports 1, 2, and 3, respectively. Writing a "1" to a bit of a port
SFR (P1, P2, or P3) causes the corresponding port output pin to switch to high. Writing a "0" causes
the port output pin to switch to low. When a port is used as an input, the external state of the port pin
will be read into the port SFR (i.e., if the external state is low, the corresponding SFR bit will contain a
"0"; if it is high, the bit will contain a "1"). The block diagrams and control registers are shown below.
E-1 Port 1
Besides general purpose I/O functions, port 1 provides the functions shown in the following table.
