For scenario 2:
Limit the supply voltage ramp up time through a series resistor (e.g. 10 Ohm) in the critical
supply path. Side effects such as voltage dips due to high current consumption of the
device need to be considered.
BSL7
BSL Module
Category
Software in ROM
Function
BSL does not start after waking up from LPMx.5
Description
When waking up from LPMx.5 mode, the BSL does not start as it does not clear the Lock
I/O bit (LOCKLPM5 bit in PM5CTL0 register) on start-up.
Workaround
1. Upgrade the device BSL to the latest version (see Creating a Custom Flash-Based
Bootstrap Loader (BSL) Application Note - SLAA450 for more details)
OR
2. Do not use LOCKLPM5 bit (LPMx.5) if the BSL is used but cannot be upgraded.

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.
