Hello,
the new PWM App 4.1.22 doesn't allow 60 MHz clock frequency: only 30 Mhz possible. The previous one 4.1.20 allow 60 MHz.
Why this?
Kind regards
Kurt

What is your chip type and periphery frequency?
The PWM frequency could not exceed a half of the periphery frequency.
For example, a XMC1 chip using 64MHz as periphery frequency could set up to 32MHz for the PWM.

Hi,
According to the reference manual, the maximum frequency is fCCUx/4. See notes of Overview section of the CCU4 or CCU8 chapters.
