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.
