15.2
The factory calibrates the internal oscillator block out-
put (HFINTOSC). However, the HFINTOSC frequency
may drift as V
directly affects the asynchronous baud rate. Two meth-
ods may be used to adjust the baud rate clock, but both
require a reference clock source of some kind.

The first (preferred) method uses the OSCTUNE
register to adjust the HFINTOSC output. Adjusting the
value in the OSCTUNE register allows for fine resolution
changes to the system clock source. See Section 2.7.1
“OSCTUNE Register” for more information.
The other method adjusts the value in the Baud Rate
Generator. This can be done automatically with the
Auto-Baud
“Auto-Baud Detect”). There may not be fine enough
resolution when adjusting the Baud Rate Generator to
compensate for a gradual change in the peripheral
clock frequency.
