CPLD_LED
4.14.3.6
CPLD_LEDS controls the state of the CPLD’s LEDs.
4.15
The four external MCF5445x interrupt requests are driven by the FPGA. The FPGA gathers four PCI
interrupts from the PCI slots, along with two pushbutton interrupts, and presents them to the MCF5445x.

4.16
The MCF5445x contains a few serial interfaces and timers that are not made available via dedicated
interfaces on the M54455EVB. However, these interfaces (and others) are brought out to a general purpose
header, J908, for easy access. The following interfaces are accessible on J908:
