Current Measurement Headers
The current of the following domains have dedicated 2-pin headers to facilitate easy current mea-
surement using an ammeter across the pins.
Note:
If a header is not loaded by default, it is bypassed using a 0-ohm resistor parallel to it. Please
make sure to remove the corresponding 0-ohm resistor (as per
) before measuring current
across the header.

Note:
When measuring P6_VDD current, make sure that the J25 jumper shunt is removed. This will
disconnect the potentiometer from VDDA and removes the leakage caused by it.
