CEn
When high, data written into the C-Channel register (address 05h) is transmitted during channel 1 on DSTo. When
low, the channel 1 timeslot is tri-stated on DSTo. Channel 1 data received on DSTi is read via the C-Channel
register (address 05h) regardless of the state of CEn. This control bit has significance only for ST-BUS operation
and is ignored for SSI operation.
When high, data written into the D-Channel Register (address 06h) is transmitted (2 bits/frame) during channel 0
on DSTo. The remaining six bits of the D-Channel carry no information. When low, the channel 0 timeslot is
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, D-channel operates at 8kb/s. When low, D-channel operates at 16kb/s (default).
When high, A-Law encoding/decoding is selected for the MT91L60/61. When low,
μ
-Law encoding/decoding is
selected.
When high, sign-magnitude code assignment is selected for the Codec input/output. When low, ITU-T code
assignment is selected for the Codec input/output; true sign, inverted magnitude (
μ
-Law) or true sign, alternate
digit inversion (A-Law).
