Definition
This pin reports an analog value proportional to the designated HS[0:3] output
current or the temperature of the GND flag (pin 14). It is used externally to
generate a ground-referenced voltage for the microcontroller (MCU) . Current
recopy and temperature feedback is SPI programmable.

Direct Inputs
The PWM frequency can be generated from IN0 pin to PWM module in case
of external clock is set.
This pin is an open drain configured output requiring an external pull-up
resistor to VDD for fault reporting.
