MOTOROLA
The COP does not generate CPU interrupt requests or DMA service
requests.
The COP is disabled in monitor mode when V
IRQ1/V
The WAIT and STOP instructions put the MCU in low-power-consump-
tion standby modes.
The COP remains active in wait mode. To prevent a COP reset during
wait mode, periodically clear the COP counter in a CPU interrupt routine
or a DMA service routine.
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.
