MOTOROLA
Stop mode turns off the CGMXCLK input to the COP and clears the COP
prescaler. Service the COP immediately before entering or after exiting
stop mode to ensure a full COP timeout period after entering or exiting
stop mode.
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.
The IRQ module remains active in wait mode. Clearing the IMASK1 bit
in the IRQ status and control register enables IRQ CPU interrupt
requests to bring the MCU out of wait mode.
The IRQ module remains active in stop mode. Clearing the IMASK1 bit
in the IRQ status and control register enables IRQ CPU interrupt
requests to bring the MCU out of stop 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.
