Looping and Shifting Data
Figure 13
configuration possibilities with the bits TSS, DPS, EN and SWAP in the registers
TSDPxy or CDAx_CR:
a) looping IOM
b) shifting data from TSa to TSb and TSc to TSd in both transmission directions (SWAP
= ’1’)
c) switching data from TSa to TSb and looping from DU to DD or switching TSc to TSd
and looping from DD to DU .
TSa is programmed in TSDP10, TSb in TSDP11, TSc in TSDP20 and TSd in TSDP21.
Data Sheet
x = 1 or 2; a,b = 0...11
gives examples for typical configurations with the above explained control and
