ADSP-2184
TIMING PARAMETERS
Parameter
IDMA Write, Short Write Cycle
Timing Requirements:
t_IKW
IACK Low before Start of Write¹
t_IWP
Duration of Write^{1, 2}
t_IDSU
IAD15–0 Data Setup before End of Write^{2, 3, 4}
t_IDH
IAD15–0 Data Hold after End of Write^{2, 3, 4}
Switching Characteristic:
t_IKHW
Start of Write to IACK High
NOTES
1_{Start of Write = IS Low and IWR Low.}
2_{End of Write = IS High or IWR High.}
3_{If Write Pulse ends before IACK Low, use specifications tIDSU, tIDH.}
4_{If Write Pulse ends after IACK Low, use specifications tIKSU, tIKH.}
