Function

Error flags set incorrectly after reset or wake-up from LPM

Description

The error flags GCCTL1.UBDIFG and GCCTL1.CBDIFG are incorrectly set after the first power-up or wake up from LPM2/LPM3/LPM4/LPM3.5/LPM4.5. If the corresponding interrupt enable bits are set, then an erroneous interrupt can be generated.

Workaround

Disable the UBDIEN and CBDIEN interrupts (GCCTL0.UBDIEN=0 and GCCTL0.CBDIEN=0) prior to entering LPM2/LPM3/LPM4/LPM4.5 . After LPM exit, re-initialize the interrupt flags only after the first FRAM access has been completed.
