LVD delay timing
Case 1: When V
(introduced by the VDD rising edge), a new ~10 ms delay starts before the release of
RESET_OUTn. See
Figure 12. LVD reset delay case 1
Case 2: When V
(introduced by the VDD rising edge), RESET_OUTn will be released immediately at the end
of the delay. No new delay is introduced in this case. See
Figure 13. LVD reset delay case 2
Case 3: When V
RESET_OUTn will be released at the end of a ~10 ms delay. See
Figure 14. LVD reset delay case 3
