      Note: The routine must handle all interrupt flags correctly. The routine must be implemented in the user code, it is not generated by Processor Expert. Find external prototypes of the ISRs in the component module header file.
  • Initialization - Initialization options of the module.
    • Output type - This setting determines the type of event output for this channel.

      There are 4 options:
      • Disabled: Channel is disabled
      • DMA request: Channel is defined as a DMA request output

    • Call Init method - The Init method of the component may be called after a power-on or reset (in initialization code) by PE.
      yes - The Init method is called by PE.
      no - The Init method is not called by PE, it should be called in the user's code.
