6.31 UCS9

UCS Module

Category

Functional

Function

Digital Bypass mode prevents entry into LPM4

Description

When entering LPM4, if an external digital input applied to XT1 in HF mode or XT2 is not turned off, the PMM does not switch to low-current mode causing higher than expected power consumption.

Workaround

Before entering LPM4:
(1) Switch to a clock source other than external bypass digital input.
OR
(2) Turn off external bypass mode (UCSCTL6.XT1BYPASS = 0).
