Version: **

Both Timer Output Module (TOM) channels, TOM0_CH0 and TOM0_CH1, share the same interrupt request (GTM_TOM0_IRQ0). However, only one Interrupt Service Routine (ISR) can be provided for these two interrupts.

This is because two adjacent TOM channels are shared. For example, TOMx_CH0 is shared with CH1, CH2 is shared with CH3, and CH4 is shared with CH5 and so on.
For details, see the “TOM and ATOM Interrupt Bundling” section in the GTM chapter in the User’s manual.

Note:       This KBA applies to the following series of AURIX™ MCUs:

  • AURIX™ TC2xx series
  • AURIX™ TC3xx series
