The MDM AP Control Register also includes a Very Low Leakage Debug Acknowledge
(VLLDBGACK) bit that is set to release the ARM core being held in reset following a
VLLS recovery. The debugger reinitializes all debug IP, and then asserts the
VLLDBGACK control bit to allow the RCM to release the ARM core from reset and
allow CPU operation to begin.
The VLLDBGACK bit is cleared by the debugger (or can be left set as is) or clears
automatically due to the reset generated as part of the next VLLS recovery.
