Three-State Timing—Bus Master/ Bus Slave
These specifications show how the memory interface is disabled
(stops driving) or enabled (resumes driving) relative to CLKIN
and the SBTS pin. This timing is applicable to bus master transi-
tion cycles (BTC) and host transition cycles (HTC) as well as the
SBTS pin.

For ADSP-21060L/ADSP-21060LC/ADSP-21062L, specification is –1.25 – DT/8 ns min, for ADSP-21062, specification is –1 – DT/8 ns min.
Strobes = RD, WR, PAGE, DMAG, BMS, SW.
For ADSP-21060LC, specification is 0.25 – DT/4 ns max.
In addition to bus master transition cycles, these specs also apply to bus master and bus slave synchronous read/write.
Memory Interface = Address, RD, WR, MSx, SW, PAGE, DMAGx, and BMS (in EPROM boot mode).
