PWM inputs

The PWM inputs PWM1 and PWM2 are direct power stage control inputs that can be

used to switch on and off one or more of the power transistors with a PWM signal

supplied to this pin. The setting of the SPI Registers CtrlReg_01 and CtrlReg_11 defines

which of the power stages will be controlled by the PWM inputs. If the selection-bits of
