Function
Transmit Multifunction Pins A to D, port 4
Depending on programming of bits PC(1:4).XPC(3:0) these
multifunction ports carry information to the system interface
or from the system to the QuadLIU
are configured to be inputs. With the selection of the
appropriate pin function, the corresponding input/output
configuration is achieved automatically. Depending on bit
SIC3.RESX latching/transmission of data is done with the
rising or falling edge of SCLKX. If not connected, an internal
pullup transistor ensures a high input level.
Each input function (SYPX, XMFS, XSIG,TCLK, XLT or XLT)
may only be selected once. SYPX and XMFS must not be
used in parallel.
Selectable pin functions as described for port 1.
