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-2106x is
the bus master accessing external memory space. These switching
characteristics also apply for bus master synchronous read/write
timing (see Synchronous Read/Write–Bus Master). If these
timing requirements are met, the synchronous read/write timing
can be ignored (and vice versa).
W = (number of wait states specified in WAIT register)
×
t
.
H = t
CK
(if an address hold cycle occurs, as specified in WAIT register; otherwise H = 0).
I = t
CK
(if a bus idle cycle occurs, as specified in WAIT register; otherwise I = 0).
NOTES

ACK Delay/Setup: User must meet t
DAAK
or t
DSAK
or synchronous specification t
SACKC
for deassertion of ACK (Low), all three specifications must be met for asser-
tion of ACK (High).
