SDT Permanent Underrun Service Enable.
When this bit is set and SDT_PERM_UNDER_STATUS is asserted, TDM_SRV is set in the
Main Status Register at 0002h.
SDT Simple Underrun Service Enable.
When this bit is set and SDT_SIMPLE_UNDER_STATUS is asserted, TDM_SRV is set in
the Main Status Register at 0002h.
UDT Loss of Signal (LOS) Status.
This bit is set when a loss of signal is detected on CSTi/LOSi. Writing a ‘0’ to this bit clears it.
This bit cannot be cleared until the TDM Control Register 1 is programmed.
UDT TDM Output Buffer Error Status.
This bit is set when there is an error in the UDT TDM output buffer. Writing a ‘0’ to this bit
clears it.
SDT TDM Output Buffer Error Status.
This bit is set when there is an error in the SDT TDM output buffer. Writing a ‘0’ to this bit
clears it.
SDT Permanent Underrun Status.
This bit is set when a permanent underrun service enable bit is set in the TDM SDT Reas-
sembly Control Structure for the port and the corresponding permanent underrun condition
occurs. Writing a ‘0’ to this bit clears it.
SDT Simple Underrun Status.
This bit is set when a simple underrun service enable bit is set in the TDM SDT Reassembly
Control Structure for the port and the corresponding simple underrun condition occurs. Writ-
ing a ‘0’ to this bit clears it.
SDT Simple Underrun Report.
Indicates the TDM channel on which a “simple underrun” occurred last.
Permanent Underrun Report. (Applies only to SDT mode.)
This register represents bits<31:16> of the 32-bit permanent underrun report. Bit<31> cor-
responds to channel 31, bit<30> corresponds to channel 30, etc.
When an underrun occurs on a certain channel, the corresponding bit is set high; the
microprocessor can clear these bits by writing them to ‘0’.
