Bits 0 to 5: Gain Control Bits 0 to 5 (GC0 toGC5). The GC0 through GC5 bits control the gain setting for the nonautomatic
gain mode. Use the tables below for setting the recommended values. The LBO (line build-out) column refers to the value in
the L0–L2 bits in LIC1 (Line Interface Control 1) register.
Bit 6: Automatic Gain Control Enable (AGCE)
Bit 7: Unused, must be set = 0 for proper operation.
