* like softmute, and zero-crossing mute are implemented. The soft Mute function can be activated in two ways: 1 Via serial bus (Mute byte, bit D0) 2 Directly on pin 28 through an I/O line of the microcontroller Very low DC stepping is obtained by use of a BICMOS technology. 44 43 42 41 40 39 38 37 36
