Computer Operating Properly Module (COP)
10.6 Computer Operating Properly Module (COP)
10.6.1 Wait Mode
The COP remains active during wait mode. If COP is enabled, a reset will occur at COP timeout.
10.6.2 Stop Mode
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 CONFIG1 register enables the STOP instruction. To prevent inadvertently turning off
the COP with a STOP instruction, disable the STOP instruction by clearing the STOP bit.
10.7 External Interrupt Module (IRQ)
10.7.1 Wait Mode
The external interrupt (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.
10.7.2 Stop 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.
10.8 Keyboard Interrupt Module (KBI)
10.8.1 Wait Mode
The keyboard interrupt (KBI) 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.
10.8.2 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.
10.9 Low-Voltage Inhibit Module (LVI)
10.9.1 Wait Mode
If enabled, the low-voltage inhibit (LVI) module remains active in wait mode. If enabled to generate resets,
the LVI module can generate a reset and bring the MCU out of wait mode.
