Data Sheet
• looping of up to four independent PCM channels from DU to DD or vice versa over the
• shifting of two independent PCM channels to another two independent PCM channels
• monitoring of up to four time slots on the IOM-2 interface simultaneously
• CPU read and write access to each PCM timeslot
The access principle which is identical for the two channel register pairs CDA10/11 and
CDA20/21 is illustrated in figure 17-3. The index variables x,y used in the following
description can be 1 or 2 for x and 0 or 1 for y. The prefix ’CDA_’ from the register names
has been omitted for simplification.

Figure 17-3 Access principle to CDA registers
To each of the four CDAxy data registers a TSDPxy register is assigned by which the
time slot and the data port can be determined. With the TSS (Time Slot Selection) bits a
time slot can be selected. With the DPS (Data Port Selection) bit the output of the CDAxy
register can be assigned to DU or DD respectively. The time slot and data port for the
output of CDAxy is always defined by its own TSDPxy register. The input of CDAxy
depends on the SWAP bit in the control registers CRx.
four CDA registers
on both data ports (DU, DD). Between reading and writing the data can be
manipulated (processed with an algorithm) by the microcontroller. If this is not the
case a switching function is performed.
