Functional Description
The AK6416A 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,
AK6416A 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.

Write
The write instruction is followed by 16 bits of data to be written into the specified address. After the 32nd
rising edge of SK to read D0 in, the AK6416A will be put into the automatic write time-out period. During the
automatic write time-out period (Busy status)and while entering write instruction, the RESET pin should be low
level. If the RESET pin is set to high level during the automatic write time-out period, the AK6416A stops
execution of internal programming and the device returns to ready status. In this case the word data of the
specified address will be incomplete. When inputting the new instructoin after RESET, the CS pin should be
set to high level. When inputting the new instruction after RESET, the CS pin should be set to high level.
When the RESET pin is kept at high level, the write is not executed. This becomes write protection function.
The CS pin need not be high level during automatic write time-out period (BUSY status).
