Community Translation: AURIX™ MCU:ISRが割り込みを逃したかどうかの確認 – KBA235225

Version: **

You can check status of the Interrupt Trigger Overflow (IOV) bit in the Service Request Control (SRC) register. This bit, if set, indicates that a service request was triggered while the Service Request Node (SRN) still had a pending service request (i.e., at least one interrupt was missed).

For more details, see the “Interrupt Router (IR)” section of the User’s manual.

Note:

This KBA applies to the following series of AURIX MCUs:

  • AURIX™ TC2xx series
  • AURIX™ TC3xx series
