Note 9: At a reset, the initial values are DSB = 0H (23 ms) and ALB [13:00] = 2000H (0dB).
Note 10: At a reset, the initial values are D1 = D2 = 0H.

ENA: Set to “H” when using independent key control or vibrato.
VIB: Set to “H” when using the vibrato function.

Command to set the cross fade level for the vibrato function on/off by adding two-byte data.
When the lower 4 bits of the data are set to 2000H, the attenuator level is 0dB. The upper two bits
The values are set in the same way as the settings for the ATTA command.
