0 EM4UNLATCH
When entering EM4, several registers will be latched in order to maintain constant functionality throughout EM4. Upon
wakeup, these registers will be reset and can have contradictory values to the latched values. To ensure a seamless transi-
tion from EM4 to EM0, the unlatch command should be given after properly reconfiguring these latched registers. The un-
latch command can be executed after any reset condition but is only needed after EM4 wakeup.
