I got bogged down in the pin table for the ZX1280n
so I spent some time on it to make it easier to understand

You are free to use the idea if you wish.
This stuff is a severe challenge for my low grade moron IQ
Particularly the section on the PWM pin numbers of the ZX1280n.
I attempted to clarify the situation with this attached kindergarten jpg.
It is multidimensional so I used color.
