PIC16(L)F1507
7.0 INTERRUPTS
The interrupt feature allows certain events to preempt
normal program flow. Firmware is used to determine
the source of the interrupt and act accordingly. Some
interrupts can be configured to wake the MCU from
Sleep mode.
This chapter contains the following information for
Interrupts:
⢠Operation
⢠Interrupt Latency
⢠Interrupts During Sleep
⢠INT Pin
⢠Automatic Context Saving
Many peripherals produce Interrupts. Refer to the
corresponding chapters for details.
A block diagram of the interrupt logic is shown in
Figure 7-1.
