PICmicros.

setup_oscillator( )
Syntax:
Parameters:
setup_oscillator(mode, finetune)
mode is dependent on the chip. For example, some chips allow speed
setting such as OSC_8MHZ or OSC_32KHZ. Other chips permit changing
the source like OSC_TIMER1.
The finetune (only allowed on certain parts) is a signed int with a range of
-31 to +31.
Returns:
Function:
Some chips return a state such as OSC_STATE_STABLE to indicate the
oscillator is stable .
This function controls and returns the state of the internal RC oscillator on
some parts. See the devices .h file for valid options for a particular device.
Note that if INTRC or INTRC_IO is specified in #fuses and a #USE
DELAY is used for a valid speed option, then the compiler will do this
setup automatically at the start of main().
