?

PB flag ?

The AUTOWAKE and PB flag bits are shown in Table 31 because they behave similarly to interrupt flags,

?

even though they are not actually related to an interrupt. These bits are set by hardware when the MPU

wakes from a push button or wake timeout. The bits are reset by writing a zero. Note that the PB flag is

set whenever the PB is pushed, even if the part is already awake.

WD_NROVF_FLAG is set approximately 1 ms before a WDT reset occurs. The flag can be cleared by

writing a zero to it and is automatically cleared by the falling edge of WAKE.

Interrupt Priority Level Structure

All interrupt sources are combined in groups, as shown in Table 32 :

Table 32: Interrupt Priority Level Groups

channel 1 interrupt

Timer 0 interrupt, External

interrupt 2

External interrupt 1, External

interrupt 3

Timer 1 interrupt, External

interrupt 4

Serial channel 0 interrupt,

External interrupt 5

External interrupt 6

Each group of interrupt sources can be programmed individually to one of four priority levels (as shown in

Table33) bysettingorclearingonebitintheSFRinterruptpriorityregister IP0 andonein IP1 (Table34).

If requests of the same priority level are received simultaneously, an internal polling sequence as shown

in Table 35 determines which request is serviced first.

Changing interrupt priorities while interrupts are enabled can easily cause software defects. It is best

to set the interrupt priority registers only once during initialization before interrupts are enabled.
