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.

Strobes = RD, WR, DMAGx.
Where N = 0.5, 1.0, 1.5 for 1:2, 1:3, and 1:4, respectively.
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, DMAGx, and BMS (in EPROM boot mode). BMS is only an output in EPROM boot mode.

During reset, the DSP will not respond to SBTS, HBR, and MMS
accesses. Although the DSP will recognize HBR asserted before
reset, a HBG will not be returned by the DSP until after reset is
deasserted and the DSP completes bus synchronization.
