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.

Function
Indirect addressing mode with the Program Counter as the source register may produce
unexpected results
Description

as the source operand, the instruction that follows immediately does not get executed.
For example in the code below, the ADD instruction does not get executed.
mov @PC, R7
add #1h, R4
