Note 1: When using double-function ports as functional I/O pins, refer the method to the relevant 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.
