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.
