Function

Device may enter lockup state during transition from AM to LPM3/4 if DCO frequency is above 2 MHz.

Description

The device might enter lockup state if DCO frequency is above 2 MHz and two events happen at the same time:

1)  The device transitions from AM to LPM3/4 (e.g. during ISR exits or Status Register modifications)

2) An interrupt is requested (e.g. GPIO interrupt).

This condition can be recovered by BOR/Power cycle.

Workaround

1. Use DCOCLK at 2MHz or lower.

OR

2. Use LPM0/x.5 instead of LPM3/4.

OR

3. Use external high-frequency crystal if it is available on the device.

OR

4. Set DCOCLK to 2MHz or lower before entering LPM3/4, then restore DCOCLK after wake-up. Note using peripherals using clocks derived from DCOCLK might be affected during this interval.
