Port P0 is an 8-bit input/output port which is also used as an external interrupt input, serial interface input/output
When used as an input port or a secondary function pins, the respective output latch (P0DR) should be set to “1”.
P0 port output latch (P0DR) and P0 port terminal input (P0PRD) are located on their respective address.
When read the output latch data, the P0DR should be read and when read the terminal input data, the P0PRD reg-
