SWO
Reference current setting resistor
connection.
The reference current is created by
connecting an external resistor to ground.
The pin voltage is about 1.0 V.
The LED driver current value can be
changed by changing this current value.
Current adjustment.
The output current can be adjusted using
the SWO pin sink current.
