Well, it has nothing to do with stopped or not.
If the new "H" value i something else then the
last read or written "H" value, you will not
get what you think into TMR0. The H-buffer
is transfered when the L-value is written,
no matter how many times you write to the
H-buffer after thar...

Anyway, to stop this kind of comments, why not
simply write them in the order recomened
by the datahseet ? :-) :-)
