Hans,

Actually, there is a significant change when "a" increments.
Going up from 7.0 mhz, MS0_P2 transitions from 0x00000 to 0xd51f8.
If they didn't somehow buffer those register writes, I should have heard it given the 10ms delays..
And from what I see on the scope, they make a very clean transition to the new frequency
without so much as a runt cycle. ?Not bad for $1.

When dumping the registers, noticed that the values don't jump much on integer transitions of "a".
The register value calculations operating on a,b,c smooth that over.
