Function

LPM3 and LPM4 currents exceed specified limits

Description

LPM3 and LPM4 currents may exceed specified limits if the SMCLK source is switched from DCO to VLO or LFXT1 just before the instruction to enter LPM3 or LPM4 mode.

Workaround

After clock switching, a delay of at least four new clock cycles (VLO or LFXT1) must be implemented to complete the clock synchronization before going into LPM3 or LPM4.
