seen by the AUXPMM and latch-up current can appear at the connected supply if:
a) Rise times are in the range of 140 kV/s (faster rise times increase probability)
b) Device operates at temperatures of 75 deg C and above (higher temperatures increase
probability)

The latch-up current disappears after complete power cycles of all supply sources.

Workaround

For scenario 1:
- Increase SVSMRRL to a level above maximum external voltage expected on AUXVCC2.
SVSMRRL = 6 or 7 (requires VCORE level of 3) is applicable for AUXVCC2 of up to
maximum voltage, 3.58V, while a lower SVSMRRL setting can be selected if a lower
voltage (e.g. 3.3V) is expected on AUXVCC2.

Or

- Connect all 3 supplies via 3 external diodes to DVCC and realize the switching externally
without using the internal AUXPMM switches. See application report

"Implementation of a

Three-Phase Electronic Watt-Hour Meter Using the MSP430F471xx"

Or

- Use AUXVCC1 instead of AUXVCC2 for backup supply

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.

Category

Software in ROM

Function

BSL request to unlock the JTAG

Description

The feature in the BSL to keep the JTAG unlocked by setting the bit
BSL_REQ_JTAG_OPEN in the return value has been disabled in this device.
