Low-Power Modes
The STOP bit in the configuration register (CONFIG) enables the STOP
instruction. To prevent inadvertently turning off the COP with a STOP
instruction, disable the STOP instruction by clearing the STOP bit.
3.8 External Interrupt Module (IRQ)
3.8.1 Wait Mode
The IRQ module remains active in wait mode. Clearing the IMASK bit in
the IRQ status and control register enables IRQ CPU interrupt requests
to bring the MCU out of wait mode.
3.8.2 Stop Mode
The IRQ module remains active in stop mode. Clearing the IMASK bit in
the IRQ status and control register enables IRQ CPU interrupt requests
to bring the MCU out of stop mode.
3.9 Keyboard Interrupt Module (KBI)
3.9.1 Wait Mode
The keyboard module remains active in wait mode. Clearing the
IMASKK bit in the keyboard status and control register enables keyboard
interrupt requests to bring the MCU out of wait mode.
3.9.2 Stop Mode
The keyboard module remains active in stop mode. Clearing the
IMASKK bit in the keyboard status and control register enables keyboard
interrupt requests to bring the MCU out of stop mode.
