Transmit Multifunction Pins A and B, port 7
Depending on programming of bits PC(1:2).XPC(3:0)
these multifunction ports carry information to the framer
interface or from the framer to the OctalLIU
TM. After
reset the ports are configured to be inputs. With the
selection of the appropriate pin function, the
corresponding input/output configuration is achieved
automatically. Depending on bit DIC3.RESX
latching/transmission of data is done with the rising or
falling edge of FCLKX. If not connected, an internal pull-
up transistor ensures a high input level.
Each input function (TCLK, XDIN, XLT or XLT) may only
be selected once.
Selectable pin functions as described for port 1.
