XPLD System Logic Device
The XPLD logic device U19, supplied by Lattice Semiconductor, is
responsible for routing resources on the phyCORE-MCF548x and
provides a very flexibly way to connect and operate application-
specific hardware components or interfaces in a target design. In
general, the XPLD device is not part of the basic processor system as
it is not needed to handle the Chip Select signal of the Flash memory
or other basic functions. This allows reprogramming of the XPLD
during runtime of the processor via the JTAG port. The XPLD JTAG
port can served by an external source (programming cable e.g.) or by
the on-board ColdFire processor over general purpose I/O pins.
The XPLD is a member of the ispXPLD 5000MX family provided by
Lattice Semiconductor (
