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

®56. 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

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.
