Configurable high/low side driver

The channels 1 to 4 can be configured as high or low side using SPI CR0: conf4_lshs. In the

low side configuration an internal clamp is present.

In high side configuration, the DRNx are connected to VB pin on PCB. To guarantee the OC

(over current) function, the DRNx voltage has to be within the range of (VB-1 V, VB+1 V).
