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 V
CC
during execution of the STP instruction.
When an input level is at an intermediate potential, a current will flow from V
CC
to V
SS
through the input-stage gate.
