During the ALC recovery operation, if the IPGA value exceeds the setting reference value by gain operation,
then the IPGA does not become larger than the reference value.
The REF7-0 bits should not be set up except for Table 21.
The data must not be written over 90H.
When PDN pin = “L”, ATTL/R7-0 bits are initialized “7FH”.
When PWN bit = “0”, the DATT holds the last setting value.
These registers are reset by PDN pin = “L” or PWN bit = “0”.

Initial value is “7FH”.
The AK5366 includes the peak hold circuit. The peak is held L/R audio data independently. These
registers are reset by reading 8bit of MSB, reading 8bit of both MSB and LSB should be continuity
controlled by reading in order of 8bit of MSB from LSB. After reading 8bit of LSB the last, 8bit of MSB
is lost by reading 8bit of LSB the last. The output value is the absolute value. Full scale is “FFFFH”.
