Description
[1]
When IAB (Ignore Address Bit) is set to 0, a playback or record operation starts from address (A0-A10). For
consecutive playback or record, IAB should be changed to a 1 before the end of that row (see RAC timing).
Otherwise the ISD4003 will repeat the operation from the same row address. For memory management, the Row
Address Clock (RAC) signal and IAB can be used to move around the memory segments.
