Control Register (P1CR) is used to specify this port for input or output. When reset, the P1CR register is initialized
to 0, with the P1 port set for input mode. The P1 port output latch is initialized to 0.

ing or falling edge.) The P10 pin can be used as an input/output port or an external interrupt input by selecting its
function with the External Interrupt Control Register (INT0EN). When reset, the P10 pin is chosen to be an input

The P1 port is a 7-bit input/output port that can be specified for input or output bitwise. The P1 Port Input/output
The P1 port is shared with external interrupt input and divider output. When using the P1 port as function pin, set
