5.1.5. MCU Power Supply Jumpers
(J18, J19, J20, J21, J22, J23)
All of the regulated power supplies are routed to the MCU daughtercard via jumpers. This allows each
power supply to be individually isolated and facilitates current measurement at the respective jumper.
Note that only the daughtercard is connected to the power lines after the jumpers so MCU current
measurements are accurate. There are an additional two jumpers that control the voltages used by EVB
peripherals connected to the VDD_HV_A and VDD_HV_B domains as described in section 5.1.7.
