The time slot and data port for the input of the CDAxy register is
defined by its own TSDPxy register. The data port for the CDAxy
input is vice versa to the output setting for CDAxy.
The input (time slot and data port) of the CDAx0 is defined by the
TSDP register of CDAx1 and the input of CDAx1 is defined by the
TSDP register of CDAx0. The data port for the CDAx0 input is vice
versa to the output setting for CDAx1. The data port for the CDAx1
input is vice versa to the output setting for CDAx0. The input
definition for time slot and data port CDAx0 are thus swapped to
CDAx1 and for CDAx1 to CDAx0. The outputs are not affected by
the SWAP bit.
