I should add the information.
Most output pins of base timers and MFTs are duplicate.
So, the PWMs that can be output are max 7ch, right?
Base Timer has maximum of 4 channels, each of which can be configured as 16-bit PWM timer. The Multi-function Timer block has 3 channels of 16-bit free-run timer. Thus we have 7 channels in total.
Yes you are correct.
