LVD delay timing

Case 1: When VDDQ reaches the VDDQ_LVD+ threshold after the first ~10 ms delay

(introduced by the VDD rising edge), a new ~10 ms delay starts before the release of

RESET_OUTn. See Figure 12.

Figure 12.

LVD reset delay case 1

Case 2: When VDDQ reaches the VDDQ_LVD+ threshold before the first ~10 ms delay

(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 VDD reaches the VDD_LVD+ threshold after the VDDQ rising edge,

RESET_OUTn will be released at the end of a ~10 ms delay. See Figure 14
