Release of

3 End of the internal reset sequence (as specified in Table 58) can only be observed by release of RESET if it is not held low

externally beyond the end of the internal sequence which would prolong the internal reset PHASE3 until RESET is released

externally.

Assertion of

5 The assertion of RESET can only trigger a reset sequence if the device was running (RESET released) before.

RESET does not gate a Destructive Reset Sequence, BIST enabled or a Destructive Reset Sequence, BIST

disabled. However, it can prolong these sequences if RESET is held low externally beyond the end of the internal

sequence (beyond PHASE3).
