Asynchronous Read/Write—Host to ADSP-2106x
Use these specifications for asynchronous host processor
accesses of an ADSP-2106x, after the host has asserted CS and
HBR (low). After HBG is returned by the ADSP-2106x, the host
can drive the RD and WR pins to access the ADSP-2106x’s
internal memory or IOP registers. HBR and HBG are assumed
low for this timing. Not required if and address are valid t
