Yes, it's 19.6608. I use them often on -20 parts, and the 9.8304 on
-10 parts or 4 * PLL with -40 parts. Sometimes for comms, and they
are good for clocks because of their divide-by-256-iveness

19.6608 doesn't get you an error-free 115200 comms unfortunately,
whether BRGH =3D 0 or 1

19660800/115200 =3D 170.666666 =3D> BRG =3D 1.6666 or 9.6666

It's OK for other baud rates though

19660800/9600 =3D 2048.00000
