is taken over into the internal PCID table.

PRC_ti - Time Interval Between two PRCs

The number written in this register must be multiplied by 1024 to get the time interval (in number of master clock

cycles ).

Clock cycles between two PRCs: Prc_ti * 1024 + 1.

Since there are maximum 50 PRCs in a 432ms frame, with the reset value of this register the PRCs in the frame

occupy the following time interval:

WARNING: This value must be greater than 8 and less than 202 to have a correct function of the PC Interface.

TSCW_Err - Action Setting After Uncorrected TSCW

Determines the behaviour in case of an uncorrected TSCC1 of a TDM frame, i.e. possible corrupted TSCW.

b1-b0:

00 =

The TSCW of the last received error free TDM frame are used for decoding the PCs

01 =

No PCs are decoded in case of TSCC1 RS uncorrected errors

10 =

The received TSCWs are used for decoding

11 =

NOT VALID.

TSCW_AddrRd - Word Address in the TSCW Table

This register addresses the word in the TSCW table the user wants to read. Whenever register Tscw_Data

(0x0657) is read, this address is automatically incremented.
