Hi,

I have tried updating CM0, CM1, SR0 and SR1 registers for immediate updating Period and dutycycle for GTM TOM and it is working, apart from this any other method to update the period and duty cycle immediately by updating only on SR0 and SR1 register.

Hi,
Please refer to section "28.14.3.1 Duty cycle, Period and Clock Frequency Update Mechanisms" in the AURIXTC3XX_um_part2_v2.0 User Manual.

Thanks for the info. Can you tell me how to reset CN0 value by another TOM channel from section 28.14.3.1 "when the reset is triggered by another TOM channel [x-1] via the signal
TRIG_[x-1]"

Hello,

You need to make EXTTRIGOUT and TRIGOUT configurations  accordingly in TOM[i]_CH[x]_CTRL register for this.

 

Thanks.
