RSLIC & CODEC CHIPSET
LREG13: PCM Data High Byte Register, Read Only (0CH)
LREG14: UTD RTIME Register, Read/Write (0DH/8DH)
LREG15: UTD RBKTime Register, Read/Write (0EH/8EH)
LREG16: UTD ETIME Register, Read/Write (0FH/8FH)
LREG17: UTD EBRKTime, Read/Write (10H/90H)
This register is used for the master processor to monitor the transmit (A to D) PCM data. For linear code, the high byte of PCM data is
sent to this register before it is transmitted to the PCM Encoder in the transmit path. For compressed code, this register is not used (in
this case, when read, a data byte of 00H will be read out).
This register is used to set the UTD Recognition Time (RTIME):
This register is used to set the UTD Recognition Break Time (RBKTime):
This register is used to set the UTD End Detection Time (ETIME):
This register is used to set the UTD End Detection Break Time (EBRKTime):

UTD_RBK[7:0] = RBKTime (ms)/4
The default value of UTD_RBK[7:0] is 19H.
RBKTime must be multiples of 4 ms. The range of it is: 0 ms ≤ RBKTime ≤ 1000 ms.
UTD_ET[7:0] = ETIME (ms)/4
The default value of UTD_ET[7:0] is 40H.
ETIME must be multiples of 4 ms. The range of it is: 0 ms ≤ ETIME ≤ 1000 ms.
UTD_EBRK[7:0] = EBRKTime (ms)
The default value of UTD_EBRK[7:0] is 64H.
The range of the EBRKTime is: 0 ms ≤ EBRKTime ≤ 255 ms.
