3.13 ATTA Command
Command to set the digital attenuator level by adding two-byte data.
When the lower
1
4 bits of the data are set to 2000H, the attenuator level is 0dB.
The upper two bits are the attenuator time constant selection bits. These bits select the soft mute
time constants.
When switching using the MUTE or KEYCON command, the value set by ATTA is also valid for the
automatic mute function.

Note 8: At a reset, the initial values are DSA 0H (23 ms) and ALA [13:00] 2000H (0dB).
The following formula determines the data ALA [

set.
