Address and vout range resistors

This section describes the locations of the Address and Vout-range pinstrap
resistors, see table 1 for the resistors for each POL position. To know what
resistor value to mount, please look in the actual technical specification of the
BMR product.

Fig 2.1 shows the positions of the address and vout range resistors.
