Start of Write = IS Low and IWR Low.
If Write Pulse ends before IACK Low, use specifications t
If Write Pulse ends after IACK Low, use specifications t
This is the earliest time for IACK Low from Start of Write. For IDMA Write cycle relationships, please refer to the ADSP-2100 Family User’s Manual, Third Edition.
