started again. The freeze signaling status could be also automatically
generated by detecting the Loss of Signal alarm or a Loss of Frame
Alignment or a receive slip (only if external register access via RSIG
is enabled). This automatic freeze signaling function is logically ored
with this bit.
The current internal freeze signaling status is available in register
SIS.SFS.
Serial Signaling Format
Only applicable if pin function R/XSIG is selected.

Setting this bit disables the timeslot assigner. With register RC1/0 the
receive frame marker could be activated during any bit position of the
current frame. This marker is active high for one 1.544-MHz cycle and
is clocked off with the falling edge of SCLKR or RCLK if the receive
elastic store is bypassed. If no SYPR has been activated since
RESET or software reset CMDR.RES the outputs of the receive
system interface assumes an arbitrary alignment.
Calculation of the value X of the “Receive Counter Offset” register
RC1/0 depends on SCLKR and on the bit position BP which should
be marked:
X = (2BP) mod 386, for SCLKR = 1.544 MHz
