Interrupts Programming Model
MSC8113 Reference Manual, Rev. 0
Freescale Semiconductor
17-41
The PIC supports both edge-triggered and level-triggered interrupt requests.
NMI
s are always
edge-triggered. The mode for the 24 programmable inputs can be defined as either edge-triggered
or level-triggered.
Note:
Unless specified otherwise in Table 17-8, MSC8113 Interrupt Routing, on page
17-19, all maskable PIC interrupt sources should be programmed as level-triggered.
Table 17-25 shows the settings for the interrupt trigger mode bit.
ELIRA defines the trigger mode and IPL for IR inputs 0 through 3.
ELIRB defines the trigger mode and IPL for IR inputs 4 through 7.
