I am having problems getting this to generate a couple of PWM outputs. Has anyone a comprehensive list of the registers that need to be initialised? Better still would be a commented example.
Many thanks.

I tried searching but couldn't find anything useful.
For example, there is a problem with PWMLER. It seems that this is only reset to zero by a match if bit 0( for MR0) is set? If I set the bits for MR5 and MR6, these remain set. If I set bit 0, all the bits are reset.
Trial and error is a very slow process.
