ADSP-21065L
Asynchronous Read/Write—Host to ADSP-21065L
Use these specifications for asynchronous host processor accesses of an ADSP-21065L, after the host has asserted CS and HBR
(low). After the ADSP-21065L returns HBG, the host can drive the RD and WR pins to access the ADSP-21065L’s IOP registers.
HBR and HBG are assumed low for this timing. Writes can occur at a minimum interval of (1/2) t
