completely tri-stated on DSTo. Channel 0 data received on DSTi is read via the D-Channel register regardless of
the state of DEN. This control bit has significance only for ST-BUS mode and is ignored for SSI operation.
When high, A-Law encoding/decoding is selected for the MT9160B/61B. When low, µ-Law encoding/decoding is

digit inversion (A-Law).
When high, data written into the C-Channel register (address 05h) is transmitted during channel 1 on DSTo. When
When high, data written into the D-Channel Register (address 06h) is transmitted (2 bits/frame) during channel 0
When high, D-channel operates at 8 kb/s. When low, D-channel operates at 16 kb/s (default).
