4 / 71 page  Pin Name Function OPT I/T O/T Description PA6/OSC1 PA6 PAPU PAWK ST CMOS General purpose I/O. Register enabled pull-up and wake-up. OSC1 CO OSC ¾ Oscillator pin PA7/RES PA7 PAWK ST NMOS General purpose I/O. Register enabled wake-up. RES CO ST ¾ Reset input VDD VDD ¾ PWR ¾ Power supply VSS VSS ¾ PWR ¾ Ground Note: I/T: Input type O/T: Output type OPT: Optional by configuration option (CO) or register option PWR: Power CO: Configuration option ST: Schmitt Trigger input CMOS: CMOS output The important point to note here is that the PB0 and PB1 pads will not be bounded to pins in the 10-pin MSOP package. These two pads default to an input state, the designer should set the register PBPU to pull high op- tions. In this way, these two internal pads can be pulled up in order to prevent input pin floating power con- sumption.
