to the size of data stored in the TMP register at the rise of the WR pulse.
When power is turned on and the RESET pulse is input, all channels are set to 0dB.
9-8 CVOL Command
The CVOL command adjusts the volume of the specified channel to the volume which corresponds
Volume can be set in 16 steps up to -30 dB in -2dB step units. Set data as shown in Table 9-10.
