CCU8 interrupts

[#1]

Hi,

What is the IRQ line for SR3 in CCU8?

I have found these settings in XMC1300.h

  CCU40_0_IRQn        =  21,   /*!< CCU40 SR0 Interrupt                      */
  CCU40_1_IRQn        =  22,   /*!< CCU40 SR1 Interrupt                      */
  CCU40_2_IRQn        =  23,   /*!< CCU40 SR2 Interrupt                      */
  CCU40_3_IRQn        =  24,   /*!< CCU40 SR3 Interrupt                      */
  
  CCU80_0_IRQn        =  25,   /*!< CCU80 SR0 Interrupt                      */
  CCU80_1_IRQn        =  26,   /*!< CCU80 SR1 Interrupt                      */
  

Why no CCU80_3_IRQn? The XMC1300 reference manual says, it has SR0-SR3 service lines.

So how to change in my code (I have to port it to CCU8)

    NVIC_SetPriority(CCU40_3_IRQn, 3);  
    NVIC_EnableIRQ(CCU40_3_IRQn);

Only the SR0 and SR1 are connected to NVIC.

You can check this in the reference manual, in the Interconnects section of the CCU8:
