Functional Description
The AK6416C has 5 instructions such as READ, WRITE, Page Write, WREN (write enable) and
WRDS (write disable). Each instruction is organized by op-code block (8bits), address block
(8bits) and data (8bits x 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, AK6416C 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.

(Note) The WRAL instruction is used for factory function test only. User can't use this
instruction.
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 AK6416C 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 AK6416C 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 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).
