Hi As i am using one of TIM8 input for external BKIN pin, to detect fault for PWM shutdwon.But How to prevent this on multiple fault events.Like any cycle by cycle protection is there.

Hi, i have configured BKIN pin to detect fault for my overcurrentSo for my motor driver if this pin sense BKIN input. How much time it be will taken by my microcontroller to sense and to act to shutdown my PWM gate signalsIs it hardware glued logic t...

ADC1_IN1ADC2_IN3ADC3_IN1 As i want to measure few signals simultaneously.can i configure by this way like ADC1, ADC2, ADC 3 or Separate channels from same ADC1

Yes you are correct its not just a crystali am connecting external clock generation IC which generates 1 MHz clock,

So can i connect 1 MHz then if lower is not mentioned at clock generated from an external source.Same for 2 MHz external clock

Our operating temperature is 180 deg C which will cause drift in internal oscillator at higher temperature.The stability is not good at higher temperature.
