Function Comparator port output toggles when entering or leaving LPM3/LPM4
Description The comparator port pin output (CECTL1.CEOUT) erroneously toggles when device
enters or leaves LPM3/LPM4 modes under the following conditions:
1) Comparator is disabled (CECTL1.CEON = 0)
AND
2) Output polarity is enabled (CECTL1.CEOUTPOL = 1)
AND
3) The port pin is configured to have CEOUT functionality.
For example, if the CEOUT pin is high when the device is in Active Mode, CEOUT pin
becomes low when the device enters LPM3/LPM4 modes.
Workaround When the comparator is disabled, ensure at least one of the following:
1) Output inversion is disabled (CECTL.CEOUTPOL = 0)
OR
2) Change pin configuration from CEOUT to GPIO with output low.

Function Using POPM instruction on Status register may result in device hang up
Description When an active interrupt service request is pending and the POPM instruction is used to
set the Status Register (SR) and initiate entry into a low power mode , the device may
hang up.
Workaround None. It is recommended not to use POPM instruction on the Status Register.
Refer to the table below for compiler-specific fix implementation information.
