Functional Description
Debug Functions
The PMC Carrier board has some additional circuitry which is not normally used, but can be used
for very low-level debugging. This circuitry includes;
• Two debug LEDs.
• A status register where the value of the interrupt signals from the PMC slots are available.
Both functions are accessed through the use of the GPIO pins on one of the P2P bridges. Contact
VMETRO for more details.
