Hi elegantk,
I found your answer below when searching for a different problem related to the CCU8 (on xmc4500).
My problem is that sometimes at setup the interrupt synchronizing my ADC and CCU8x stops.
The problem comes and goes between compilations if I include/remove dummy code in the setup code (changing the setup timing).
My question is why do you run the code "for(delay=0;delay<10000;delay++);" before you execute "CCU80 Global start enable".
I thought the global start was not active until I retrieve the CCU8x from idle mode.
Is there a known timing problem?

Hi Aaron,
When the Event 2 is connected to SCU.GLCCST80, it does not use up any pin.
Please try out the following code.
Assume that PWMSP002 using P0.5 & P0.2. (CCU80.CC80)
Do not setup the TRAP in the UI configuration.
status = PWMSP002_Start(&PWMSP002_Handle0);
CCU80_CC80->INS|= (7<<8); // Event 2 to CCUCON
CCU80_CC80->INS|= (7<<0); // Event 0 to CCUCON
CCU80_CC80->INS|= (1<<16); // Event 0 rising edge
CCU80_CC80->CMC|= (1<<17); // TS = 1
CCU80_CC80->CMC|= (1<<2); // ENDS = Event 0
CCU80_CC80->TC|= (0xF<<17); // TRAPE0,1,2,3
for(delay=0;delay<10000;delay++);
SCU_GENERAL->CCUCON |=(1<<8);
