timer counter input, set the P0OUTCR register's corresponding bit to 0 after setting the P0DR to 1. The P0 port has
independent data input registers. To inspect the output latch status, read the P0DR register. To inspect the pin status,
read the P0PRD register.

P0 (P07 to P00) Port (High Current)
The P0 port is an 8-bit input/output port shared with external interrupt input, serial expansion interface input/output,
When reset, the output latch (P0DR) and the push-pull control register (P0OUTCR) are initialized to 1 and 0,
The P0 port allows its output circuit to be selected between N-channel open-drain output or push-pull output by the
The P0 port has programmable internal Pull-up resistance to be controlled by P0PUCR registers.
When using this port as a port input, external interrupt input, serial expansion interface input, UART1 input and
In the serial PROM mode, P01 pin used as a BOOT/RXD1 pin, P00 pin used as a TXD1 pin. For details, see "Serial
