Notes1: 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 po-
tential, a current will flow VCC to VSS through the input-stage gate.
