P0 (P07 to P00) Port (High Current)
The P0 port is an 8-bit input/output port shared with external interrupt input, SEI serial interface input/output,
When reset, the output latch (P0DR) and the push-pull control register (P0OUTCR) are initialized to 1 and 0, re-
When using this port as an input port, set the P0OUTCR register's corresponding bit to 0 after setting the
