I have a board designed for a generic 80C32 for which I am writing some
software. For some reason the supplier sourced and fitted Atmel TS80C32X2
parts which seem to have a few 'issues'.

The processor runs on an 11.0592MHz crystal and I need to run its serial
port at 19k2 baud.

I use timer 1 in mode 2 (8 bit auto reload) which ought to require a reload
value of 0xFD for 19k2 baud but actually requires a reload value of 0xFC to
get 19k2.

I use timer 0 in the same mode as an interrupt generator and it appears not
to have the same out by one problem.

I did not find anything in the data *** errata about this problem.

Anyone else experienced this?
