Notes1: For details usage of double-function ports as function I/O ports, refer to the applicable sections.
2: Make sure that the input level of each pin should be either 0 V or VCC in STP mode.
When an input level is at an intermediate voltage level, the ICC current will become large because of the input buffer gate.
