ADSP-21161N
Asynchronous Read/Write – Host to ADSP-21161N
Use these specifications for asynchronous host processor accesses
of an ADSP-21161N, after the host has asserted
CS
and
HBR
(low). After
HBG
is returned by the ADSP-21161N, the host can
drive the
RD
and
WR
pins to access the ADSP-21161N’s IOP
registers.
HBR
and
HBG
are assumed low for this timing.
Although the DSP will recognize
HBR
asserted before reset, a
HBG
will not be returned by the DSP until after reset is deas-
serted and the DSP completes bus synchronization.
Note
:
Host internal memory access is not supported.
