Memory Write—Bus Master
Use these specifications for asynchronous interfacing to memo-
ries (and memory-mapped peripherals) without reference to
CLKIN. These specifications apply when the ADSP-21061 is the
bus master accessing external memory space in asynchronous
access mode. Note that timing for ACK, DATA, RD, WR, and
DMAGx strobe timing parameters only applies to asynchronous
access mode.

W = (number of wait states specified in WAIT register) × tCK.
H = tCK (if an address hold cycle occurs, as specified in WAIT register; otherwise H = 0).
I = tCK (if a bus idle cycle occurs, as specified in WAIT register; otherwise I = 0).
1 ACK delay/setup: User must meet tDAAK or tDSAK or synchronous specification tSAKC for deassertion of ACK (low), all three specifications must be met for assertion of ACK
(high).
2 The falling edge of MSx, SW, BMS is referenced.
3 For more information, see Example System Hold Time Calculation on Page 43 for calculation of hold times given capacitive and dc loads.
