= IDAC • 3.9µA (∼1mA full-scale). Setting (PDCON.PDIDAC) will shut down IDAC and float the IDAC pin.
Interrupt Priority (IP)

SFR B8h 1 0 0 PS0 PT1 PX1 PT0 PX0 80h
PS0 Serial Port 0 Interrupt. This bit controls the priority of the serial Port 0 interrupt.
bit 4 0 = Serial Port 0 priority is determined by the natural priority order.
1 = Serial Port 0 is a high-priority interrupt.
PT1 Timer 1 Interrupt. This bit controls the priority of the Timer 1 interrupt.
bit 3 0 = Timer 1 priority is determined by the natural priority order.
1 = Timer 1 priority is a high-priority interrupt.
PX1 External Interrupt 1. This bit controls the priority of external interrupt 1.
bit 2 0 = External interrupt 1 priority is determined by the natural priority order.
1 = External interrupt 1 is a high-priority interrupt.
PT0 Timer 0 Interrupt. This bit controls the priority of the Timer 0 interrupt.
bit 1 0 = Timer 0 priority is determined by the natural priority order.
1 = Timer 0 priority is a high-priority interrupt.
PX0 External Interrupt 0. This bit controls the priority of external interrupt 0.
bit 0 0 = External interrupt 0 priority is determined by the natural priority order.
1 = External interrupt 0 is a high-priority interrupt.
Enable Wake Up (EWU) (Waking Up from Idle Mode)
7 6 5 4 3 2 1 0 Reset Value
SFR C6h — — — — — EWUWDT EWUEX1 EWUEX0 00h
Auxiliary interrupts will wake up from Idle mode. They are enabled with EAI (EICON.5).
EWUWDT Enable Wake Up Watchdog Timer. Wake using watchdog timer interrupt.
bit 2 0 = Do not wake up on watchdog timer interrupt.
1 = Wake up on watchdog timer interrupt.
EWUEX1 Enable Wake Up External 1. Wake using external interrupt source 1.
bit 1 0 = Do not wake up on external interrupt source 1.
1 = Wake up on external interrupt source 1.
EWUEX0 Enable Wake Up External 0. Wake using external interrupt source 0.
bit 0 0 = Do not wake up on external interrupt source 0.
1 = Wake up on external interrupt source 0.
