CMI
Select CMI Precoding
Only valid if CMI code (FMR0.XC1/0=01) is selected. This bit defines
the CMI precoding and influences only the transmit data and not the
receive data.

Rising Edge Synchronous Pulse Transmit
Depending on this bit all transmit system interface data and marker
are clocked off or sampled with the selected active edge.

The SYPX pin function is selected by PC(1-4).XC(2-0) = 0000.
Rising Edge Synchronous Pulse Receive
Depending on this bit all receive system interface data and marker are
clocked off with the selected active edge.

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
by pin XSIG. XSIG is selected by PC(1-4).XPC(2-0).
