Register
2: When the wake-up is due to an interrupt and the GIE bit is set, the PC is loaded with the interrupt vector
3: Table 6-3 lists the RESET value for each specific condition.
4: On any device RESET, these pins are configured as inputs.
5: This is the value that will be in the port output latch.
