Notes 1 : 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.
