1.5 Volume Setting Register Data (Command Types)
The data in the volume setting registers is written and read based on 6-bit parallel data that is input and output via the
DATA5 to DATA0 pins when the SELR pin is set for high level input. The data (commands) in the various volume setting
registers are described below.

D4 to D0 indicate the data used to control gain in the IN1L register’s input signal, with codes corresponding
to the gain levels listed in Table 1-1 below. When D5 is “1”, mute mode is set.
