Community Translation: AURIX™ MCU: 最大および最小の割込み応答時間 – KBA235187

Version: **

The minimum response time for an interrupt is eight cycles:

  - Two cycles for arbitration
  - Four cycles for context save
  - Two cycles for jump to address

The maximum response time of an interrupt is endless (for example, if an interrupt with higher priority is at work).

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
