Hello @Pedram​ ,

It's not possible to trigger the timer 3 from timer 1 through channel 1 and channel 2 in the same time.

The source of trigger output of timer1 should be one of these:

• Reset
• Enable
• Update
• Compare Pulse (CC1IF)
• Compare - OC1REF
• Compare - OC2REF
• Compare - OC3REF
• Compare - OC4REF

You can refer to the "Timer synchronization" section in the reference manual relevant to your device.

Regards,
