P5V0 (+5.0V Switching Power Supply) is selected for the
VDD_HV_A_MCU reference
Default
closed
2-3
P3V3_DC_SW (+3.3V Switching Power Supply) is selected
for the VDD_HV_A_MCU reference
OPEN
VDD_HV_A domain is isolated and unpowered
J24
1-2
The shunt resistor R57 [0.2 Ohms] is selected for current
measurement proposals on the VDD_HV_A_MCU reference
2-3
The shunt resistor R58 [1 Ohms] is selected for current
measurement proposals on the VDD_HV_A_MCU reference
Default
closed
OPEN
The shunt resistors R57 and R58 are disabled for current
measurement proposals on the VDD_HV_A_MCU reference
J25
1-2
VDD_HV_A is routed to VDD_HV_A_MCU reference. A
jumper on this position disables the shunt resistors R57 and
R58 are disabled for current measurement proposals.
Default
closed
OPEN
This jumper allows a differential measurement to the shunt
resistor in series for the VDD_HV_A_MCU domain.
