ADV611/ADV612
Host Interface (Compressed Data) Register Timing
The diagrams in this section show transfer timing for host read and write transfers to the ADV611/ADV612’s Compressed Data
register. Accesses to the Compressed Data register are faster than access timing for the Indirect Address, Indirect Register Data, and
Interrupt Mask/Status registers. For information on access timing for the other registers, see the Host Interface (Indirect Address,
Indirect Register Data, and Interrupt Mask/Status) Register Timing section. Also note that as long as your system observes the RD
or WR signal assertion timing, your system does NOT have to wait for the ACK signal between new compressed data addresses.
