Hi,

I would like to route the TOM Channels to TIM as I would like to generate an interrupt with PWM raising edge.

Is it possible to route the TOM Channels to TIM. If yes could you please give the solution for this query

Hi Atharva,

Please refer to the below code example available in the GitHub:

Hi Atharva,

According to AURIX TC3xx User Manual (see link below) Chapter 28.4.1 Overview -> Figure 9 TIM auxiliary input multiplexing, the channel has to be fixed, (i.e., TOM0 can only connect to TIM0) in other words a (A)TOMx_Chy can be connected to TIMx_CHy and no other TIM channels for your use case.

The configuration is defined in CCMx defining the Source Selection Register AUX_IN_SRC for TIMx_Chy
