The Kinetis Errata for 3N96B mask set has this erratta.......

 

--------------------------------------------------------

e5952: SMC: Wakeup via the LLWU from LLS/VLLS to RUN to VLPR incorrectly

triggers an immediate wakeup from the next low power mode entry

Errata type: Errata

Description: Entering VLPR immediately after an LLWU wakeup event from LLS/VLLS, will cause any

subsequent entry into LLS/VLLS to fail if entry into VLPR mode occurs before clearing the

pending LLWU interrupt.

Workaround: After an LLWU wakeup event from LLS/VLLS, the user must clear the LLWU interrupt prior to

entering VLPR mode.

-------------------------------------------------------

 

Does this errata also affect wakeup/re-entry into VLLS2 after being in VLPR?  Thanks in advance for any clarification provided.
