The ADC supports the following 7 inputs: • PS, PF, PR, PGND, used for on-demand conversions and by the diagnostic routine • VRCM, used by the diagnostic routine • ERBST, used for on-demand conversions and by the diagnostic routine • GND, used for on-demand conversions and by the diagnostic routine The ADC is designed to convert any of the following 7 paths: • PS vs PGND • PF vs PGND • PR vs PGND • PF vs PR in high resolution (pre-deployment), with IPF_PU and IPR_PD enabled • PF vs PR in low resolution (post deployment), with IPF_PU and IPR_PD enabled • ERBST vs GND • VRCM vs GND (VRCM enabled) The ADC conversion formula is the following: VADC=LSB×CODE (8) Where LSB is VADC_LSB_x (according to conversion requested) and CODE is a 10-bit signed word.
