RTS values are generated as follows:
Figure 77
The transformation of RTS values in a clock is not specified in the SRTS specifications.
Basically (the implementation is slightly different), the ICRC calculates another RTS
value based on the transmit clock. The difference between received RTS values and
locally calculated RTS values, drives a DCO. This solution can be described as a PLL
with an unusual phase comparator.
