Hi,
We are using Relax KIT XMC4500 and Dave 3.1.4 date 5.11.2012.

We would like to setup the SVM PWM modulator in such a way that CC80/0 would have phase 1 (U) PWM1H,PWM1L, CC81/0 would have phase 2 (V) PWM2H,PWM2L, CC82/0 would drive phase 3 (W) PWM3H,PWM3L,
We would like to use pins P0.0 - P0.5, which should be possible. The signals should use CCU80.0x, CCU80.1x,CCU80.2x, where x is only 0 and 1.

The C80/1, C81/1, C81/2 are used for other purposes.

The issue is that IO002/5 uses pin P0.11 and IO002/4 uses pin P0.6. which isCCU80.OUT31 and CCU80.OUT30.

Via manual signal assigment we have following:

Hi,
If I understand correctly, you would like to use P0.11 (CCU80.OUT31) & P0.6 (CCU80.OUT30) to drive phase 3. In this case, you need to use P0.1 (CCU80.OUT11) & P0.4 (CCU80.OUT10) to drive phase 1 and P0.0 (CCU80.OUT21) & P0.3 (CCU80.OUT20) to drive phase 2. The reason is that the 3 time slices used for driving 3 phases must be consecutive.

Hello, how would be best to use CCU80 in such a way, that would be possible to drive 3 phase pwm modulation and on top of that implementing measurement of for each phase switching delay. For example when phase1 switches from 0 to 1, command is given to driver, and what would be best used to measure that delay betwen reference switching (output to Gate of the switching element) and actual switching middle- input (digital) at Udc/2.

My idea is to use: CC80/0 would have phase 1 (U) PWM1H,PWM1L, CC81/0 would have phase 2 (V) PWM2H,PWM2L, CC82/0 would drive phase 3 (W) PWM3H,PWM3L, time would be measured with CC80/1, CC80/2 and CC80/3 at each corresponding phase using External capture.
