Pad Description
Pad Name RES I/O I Schmitt trigger reset input. Active low Bidirectional 2-bit input/output port. Each bit can be a wake-up input. The PA0 and PA1 are pin-shared with the BZ and BZ, respectively. Once the PA0 and PA1 are selected as buzzer driving outputs, the output signals come from an internal buzzer clock generator. Software instructions determine the CMOS output or Schmitt trigger input with pull-high resistor Function
