I'm hoping that I've missed something in the data sheet or errata...

I'm having some weird problems generating a correct baud rate of 
19,200.  What is weird is that this *was* working, and has stopped for 
some reason.  It is apparently code-related as I've swapped an entirely 
new circuit board and processor in with the same results.
I have an application which uses a PIC18 serial port at 19,200  (I'm 
currently using a '2620, but have tried with others as well).    I'm 
clocking the PIC at 25Mhz (External clock source).

With BRG16=0, the closest I can get to 19,200 is 19290, or 0.47% 
error.   As the other end of this link is a 'F887 running on the 
internal RC oscillator, I'd really like to shave every little bit of 
error off of the 18F side with the 20ppm XTAL....   So I figured I'd 
turn on BRG16 and BRGH and set the value of SPBRG/SPBRGH to 325, which 
should generate a baud rate of 19171, and reduce the error to 0.15%.

Imagine my surprise when I discovered the baud rate was actually closer 
to 22.6kb/s.

I have dug through the data sheets and errata and haven't found anything 
which indicates that this shouldn't work.   What am I missing?  Or does 
this just not work with a 25Mhz clock on a PIC18LF....
