RUNIN Length. The RUNIN length is equal to PLL-start-value
calculation time. This means
that the shorter RUNIN length decreases the data rate offset calculation
accuracy and symbol synchronization found signal generation stability.
Note that the RUNLEN have to be changed together with the TSI
configuration registers.
