Always reads ‘0’.
UDT Loss of Signal (LOS) Service Enable.
When this bit is set and UDT_LOS_STATUS is asserted, TDM_SRV is set in the Main Status
Register at 0002h.
UDT TDM Output Buffer Error Service Enable.
When this bit is set and UDT_TDM_OUT_BUF_STATUS is asserted, TDM_SRV is set in
the Main Status Register at 0002h.
SDT TDM Output Buffer Error Service Enable.
When this bit is set and SDT_TDM_OUT_BUF_STATUS is asserted, TDM_SRV is set in
the Main Status Register at 0002h.
SDT Reassembly Circular Buffer Base Address. (Applies only to SDT mode.)
Represents bits<19:15> of the SDT Reassembly Circular Buffer word address in external
memory.
Always reads “00_000”.
Play old data or silence byte on underrun. (Applies only to SDT mode.)
‘0’ = During a TDM underrun, the reassembly process outputs silence bytes (programmed
in the MAINTDM1 register at 6000h) on DSTo.
‘1’ = During a TDM underrun, the reassembly process replays the reassembly circular
buffer.
Reassembly TDM Output Clock Polarity.
‘0’ = TDM data is driven out on the falling edge of SToCLK or C4M_C2M
‘1’ = TDM data is driven out on the rising edge of SToCLK or C4M_C2M.
In ST-BUS, this bit must be set to “0”
Outgoing Loss of Signal. (Applies only to UDT mode.)
CSTo/LOSo pin drives out the value programmed in this field.
Reassembly TDM port control.
‘0’ = Port is not active (output data pins are held in high impedance).
‘1’ = Port is active.
Reassembly Internal Enable Process.
‘0’ = Process is disabled.
‘1’ = Process that transfers data/CAS from the TDM output buffer to the output pins is
enabled.
Reassembly External Enable Process. (Applies only to SDT mode.)
‘0’ = Process is disabled.
‘1’ = Process that transfers data/CAS from external memory to the TDM output buffer is
enabled.
