Memory Read—Bus Master
Use these specifications for asynchronous interfacing to memories (and memory-mapped peripherals) without reference to CLKIN.
These specifications apply when the ADSP-21065L is the bus master when accessing external memory space. These switching
characteristics also apply for bus master synchronous read/write timing (see Synchronous Read/Write—Bus Master below). If these
timing requirements are met, the synchronous read/write timing can be ignored (and vice versa). An exception to this is the ACK pin
timing requirements as described in the note below.

W = (number of wait states specified in WAIT register)
tCK.
HI = tCK (if an address hold cycle or bus idle cycle occurs, as specified in WAIT register; otherwise HI = 0).
H = tCK (if an address hold cycle occurs as specified in WAIT register; otherwise H = 0).
NOTES
1Data Delay/Setup: User must meet t
DAD or to tDRLD or synchronous specification tSSDATI.
2The falling edge of
MSx, SW, BMS, are referenced.
3ACK is not sampled on external memory accesses that use the Internal wait state mode. For the first CLKIN cycle of a new external memory access, ACK must be
valid by tDAAK or tDSAK or synchronous specification tSACKC for wait state modes External, Either, or Both (Both, if the internal wait state is zero). For the second and
subsequent cycles of a wait stated external memory access, synchronous specifications t SACKC and tHACKC must be met for wait state modes External, Either, or Both
(Both, after internal wait states have completed).
