Functional Description
The AK6420A/40A/80A 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, AK6420A/40A/80A 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.
