Note1 : 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.
