PIC16(L)F1826/27
26.2
The factory calibrates the internal oscillator block out-
put (INTOSC). However, the INTOSC frequency may
drift as V
affects the asynchronous baud rate. Two methods 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 INTOSC output. Adjusting the
value in the OSCTUNE register allows for fine resolution
changes to the system clock source. See
“Internal Clock Sources”
The other method adjusts the value in the Baud Rate
Generator. This can be done automatically with the
