FRMFB[0] is used for frame and multiframe synchronization in
receive and transmit direction of all ports. FRMFB[1:7] are
unused
FRMFB[N] is used for frame and multiframe synchronization in
receive and transmit direction of corresponding ports
Pin SDI is used for RTS
RTS data are generated by ICRC
Pins FTCKO are used as transmit clock (FTCKO[0:7] are input
pins)
Clock of ICRC is used as transmit clock and is also switched to
FTCKO pins (FTCKO[0:7] are output pins)
FTMFS is active low
FTMFS is active high
