In case the user wishes to utilize the Current Sense/MultiSense function of the device, it is
necessary to plug a sense resistor in R_SENSE.
The package includes a through-hole resistor, to be mounted on TP1-TP2 (see Figure 4:
"Mounting through-hole sense resistor").
Different R_SENSE values can be adopted based on user preference.
