output. This port is switched between input and output modes using the P1 port input/output control register (P1CR).
When reset, the P1CR register is initialized to 0, with the P1 port set for input mode. Also, the output latch (P1DR) is
initialized to 0 when reset.

Port P1 is an 6-bit input/output port shared with external interrupt input, timer/counter input/output, and divider
Note 1: When a read instruction is excuted on P1 port, indeterminate values are read in from bits 7 to 6.
Note 2: *: Don’t care
