from mute to the original volume value after a filter-mode change according to the settings of the Soft and
Zero Cross bits in the Mode Control 3 register. When disabled, an immediate mute and unmute is per-
formed.

Loss of clocks or a change in the FM bits will always cause an immediate mute; unmute in these condi-
tions is affected by the RMP_UP bit.

Note:

For best results, it is recommended that this feature be used in conjunction with the RMP_UP bit.

Mixing Control Pair 1 (Channels A1 & B1)(Address 06h)
Mixing Control Pair 2 (Channels A2 & B2)(Address 09h)
Mixing Control Pair 3 (Channels A3 & B3)(Address 0Ch)
Mixing Control Pair 4 (Channels A4 & B4)(Address 0Fh)

6.6.1

Channel A Volume = Channel B Volume (A=B)

Default = 0
0 - Disabled
1 - Enabled

Function:

The AOUTAx and AOUTBx volume levels are independently controlled by the A and the B Channel Vol-
