VTM has a general purpose retention interface, consistent of 16 sets of 3 signals that can operate totally independently in order to provide retention for 16 signals in the SoC:
The input LPMODE_SLEEP_RETIN[n] is sampled and synchronized continuously while LPMODE_SLEEP_RETEN[n] = 0. The synchronized output is send out via LPMODE_SLEEP_RETOUT[n]. Once LPMODE_SLEEP_RETEN[n] = 1, then the synchronizer will latch the value and continue providing that latched value via LPMODE_SLEEP_RETOUT[n].
