NOTES
1Start of Write =
IS Low and IWR Low.
2If Write Pulse ends before
IACK Low, use specifications t
IDSU, tIDH.
3If Write Pulse ends after
IACK Low, use specifications t
IKSU, tIKH.
4This is the earliest time for
IACK Low from Start of Write. For IDMA Write Cycle relationships, please refer to the ADSP-21xx Family User’s Manual, Third Edition.
