Functional Description
The AK6420B/40B/80B has 4 instructions such as READ, WRITE, WREN (write enable) and WRDS (write
disable). Each instruction is organized by op-code block (8bits), address block (8bits) and data (8bits
2).
When input level of SK pin is high level and input level of chip select (CS) pin is changed from high level to low
level, AK6420B/40B/80B can receive the instructions.
When the instructions are executed consecutively, the CS pin should be brought to high level for a minimum of
250ns(Tcs) between consecutive instruction cycle.
