Notes1: For details of the functions of ports P0 to P3 in modes other than single-chip mode, and how to use double-function ports as function I/O ports, refer
to the applicable sections.
2: Make sure that the input level at each pin is either 0 V or VCC during execution of the STP instruction.
When an input level is at an intermediate potential, a current will flow from VCC to VSS through the input-stage gate.
