The TstPatCmp can be enabled to receive either static pattern or pseudo random pattern from
a remote generator.
In case of the Interior (Regs have indize 0) comparator it is connected to an outgoing timeslot
of the TSI.
In case of the Exterior (Regs have indize 1) comparator it is connected to an incoming timeslot
into the TSI.
The TSI timeslot is selectable between 0 and 65535.
The TstPatCmpBlk includes a PRBS pattern comparator (eleven stage LFSR with taps at the 9th
and 11th stage).
The pattern comparator is able to synchronize itself to the receive bit stream. After
synchronization 125 μs-frames and errors are counted.
A time of 125us delay has to be taken into account, till the comparator has stopped after
resetting TstPatCmpRxPatEn bit in TstPatCmpCtrlReg.
