Note: ATT* is data bits for the attenuation level.
GAI* is data bits for the gain level.
IMPORTANT: There is the compatibility between the AK4531 and AK4532. But the input mixer
functions of those device has some different implication in the application, receptively.
And the other address of control register except those described in the above table and “1A” are
“do not care”. Address “1A” for testing shall be strictly prohibited to access.
Be ware that the three MSB address bits(A7, A6, A5) are ignored by AK4532. Writing to address
“20” register will update the address “00” register for instance.
