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.
