The SYPR pin function is selected by PC(1-4).RPC(2-0) = 000.
TTR Register Function
Setting this bit the function of the TTR1-4 registers are changed. A
one in each TTR register will force the XSIGM marker high for the
respective time-slot and controls sampling of the time-slots provided
on pin XSIG. XSIG is selected by PC(1-4).XPC(2-0).

DCO-R Synchronization Clock Source
These bits select the reference clock source for the DCO-R circuitry.
00… receive reference clock generated by the DPLL of channel 1
01… receive reference clock generated by the DPLL of channel 2
10… receive reference clock generated by the DPLL of channel 3
11… receive reference clock generated by the DPLL of channel 4
Note: After Reset all DCO-R circuitries will synchronize on the clock

SYPR is latched with the first falling edge of the SCLKR clock.
SYPR is latched with the first rising edge of the SCLKR clock.
Signaling is automaticly frozen if one of the following alarms

signaling buffer is also done if one of the above described alarm
conditions is active. However, updating of the signaling buffer is
stopped if SIC2.FFS is set. Significant only if the serial signaling
access is enabled.

configured individually.
If LIM0.MAS is set the DCO-R circuitry will synchronize on the
clock applied to port SYNC.
