Summarizes features: edge/level sensitivity and ISR execution timing.
Illustrates the internal structure of an external interrupt channel with edge detection.
Depicts interfacing external interrupt pins with circuitry, including debounce.
Contains bits to enable or disable external interrupt channels.
Flags indicate interrupt events; cleared by ISR.
Configures interrupt detection type: level or edge sensitive.
Ensures interrupt pin is set to digital input mode before enabling.
Provides sample C code to initialize and set up External Interrupt Channel 0.
Addresses bouncing switches using edge detection and software debounce.
Illustrates event sequence for disturbed input signals with a timer.
Discusses using interrupts with DMA, needing hardware debounce for disturbed signals.
Explains using external interrupts to request stop mode and wake the MCU.
Demonstrates Interrupt 0 waking MCU from stop, Interrupt 1 requesting stop.
Shows Interrupt 0 requesting stop mode and waking MCU without an ISR.
