Hi,

I am working on the TC297 Aurix controller and have a query regarding the GTM based TOM module where I would like to generate an interrupt at the TOM PWM raising edge, Is it possible ? If yes could you please give the solution for that.

Hello Atharva,

TOM pwm is generated from the comparison between a counter register "CN0" and 2 compare "CM0" and "CM1". Every compare match lead to an output edge.

Please read 28.14.3 TOM Channel of AURIXTC3XX_um_part2_v2.0.pdf.

You can the generate an ISR request for both CCU1 and CCU0 compare match. See 28.14.8.16Register TOM[i]_CH[x]_IRQ_NOTIFY.

Prudhvi.
