Select Corner Frequency of DCO-R
Setting this bit reduces the corner frequency of the DCO-R circuit by
the factor of ten to 0.6 Hz.
Reducing the corner frequency of the DCO-R circuitry increases the
synchronization time before the frequencies are synchronized.

which is synchronized with the extracted receive route clock. In this
configuration the transmit elastic buffer has to be enabled. Refer to
register FMR5.XTM. For correct operation of loop timed the remote
loop (bit LIM1.RL = 0) must be inactive.

Jitter attenuation of the transmit clock is done using an external
pullable crystal between pins XTAL3/4
Jitter attenuation of the transmit clock is done without using an
external pullable crystal between pins XTAL3/4. Only a free
running 12.352-MHz clock has top be provided at XTAL3 (+/-
50 ppm).
Jitter attenuation of the system/transmit clock is done using an
external pullable crystal between pins XTAL1/2
Jitter attenuation of the system/transmit clock is done without
using an external pullable crystal between pins XTAL1/2. Only
a free running 16.384-MHz clock has top be provided at XTAL1.
normal operation
Transmit clock is generated from the clock supplied by XTAL3
(register PCR) is detected during the time interval which is
defined by register PCD.
alarm is only cleared if the pulse density is fulfilled and no more
than 15 contiguous zeros are detected during the recovery
interval. (according to TR-NWT 499).
and no more than 99 contiguous zeroes are detected during the
recovery interval (according to TR-NWT 820).
