I'd like to think so, but it's somewhat niche (Baremetal that is)
however...

... my use is the RISC-V cores in the rp2350, so bare metal RISC-V
asembly.... But the principle for programming the PWM generators
is more or less the same from eith CPU, so I understand, but it's
something I've not gotten round to.

I'd suggest to have a look at the manual and SDK and see how to do it
from C then hand translate the C code into ASM...
