Definition
This pin reports an analog value proportional to the designated HS[0:3] output
Monitoring
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.

Fault Status
Each direct input controls the device mode. The IN[0 : 3] high side input pins
are used to directly control HS0 : HS3 high side output pins.
The PWM frequency can be generated from IN0 pin to PWM module in case
the external clock is set.
This pin is an open drain configured output requiring an external pull-up
(Active Low)
resistor to V DD for fault reporting.
