Data Access via CDAx0 and CDAx1 register pairs
2.2.2.1.1 Looping and Shifting Data
Figure 23 gives examples for typical configurations with the above explained control and
configuration possibilities with the bits TSS, DPS, EN and SWAP in the registers
TSDPxy or CDAx_CR:
a) looping IOM-2 time slot data from DU to DD or vice versa (SWAP = ’0’)
b) shifting data from TSa to TSb on DU and DD (SWAP = ’1’)
c) switching data from TSa (DU) to TSb(DD) and TSb (DU) to TSa (DD)
x = 1 or 2; a,b = 0...11
