2.6.2 VC5505 EVM Power Domain Probe Points
The VC5505 EVM has pre-designed probe points in the circuitry which could be used to
observe power domains. These measurement points consist of a 2 pin 0.1 inch spaced
printed circuit board (pcb) footprint jumper shorted by a zero ohm resistor. The probe
points are shown in the table below.
