The AMODE command uses 2 bytes. This command is used to perform various settings for analog circuitry.
This command is not available during power-down state, transition to power-up state, transition to power down
state or playback state.
In the case of performing power down using PDWN command during power up of analog circuitry, the setting of
power up by AMODE command is retained. Use the AMODE command to perform power down, if need to
use different conditions from power up of analog circuitry.
In the case of power up of analog circuitry, input the AMODE command after setting the CVOL command to
“00h” (: initial value).
The settings of each bit is shown below.
The setting is initialized by reset release or power-up.
The FAD bit specifies whether to perform fade-out processing when the STOP command is input. If the bit is
set to “1”, fade-out processing is performed during a period of approx. 3 ms after the STOP command is input.
The BUSYB signal goes to “H” level after fade-out processing.

The DAG1, 0 bits are used to set the gain of the internal DAC signal. The AIG1, 0 bits are used to set the gain
of an analog input signal from the AIN pin. They are available only when using the speaker amplifier.
