When high, the FDI port operates in ST-BUS mode. When low, the FDI operates in SSI mode.
When high, data written into the C-Channel register (address 14h) are transmitted during channel 1 on DSTo.
When high, data written into the D-Channel Register (address 15h) are transmitted during channel 0 on DSTo.
When high, the D-Channel operates at 8 kb/s.
When low, the D-Channel operates at 16 kb/s default.
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 14h) regardless of the state of CEN. This control bit has significance only for ST-BUS
operation and is ignored for SSI operation.
When low, the channel 0 timeslot is 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.
