dsPIC33CH Vs dsPIC33F divide.

The new dsPIC33CH parts have a 6 cycle divide whereas the older dsPIC33F takes 18 cycles. The number of cycles is not data dependent.

So I guess more Silicon for fewer cycles, but used how?

For the Newton-Raphson method, a better initial guess will reduce the number of steps
