Function
Transmit Multifunction Port A to D
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 FALC
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
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 or
TCLK) may only be selected once. SYPX and
XMFS must not be used in parallel.
Selectable pin functions are described below.
