3.2
The OSCCON register (Register 3-1) controls the main
aspects of the device clock’s operation. It selects the
oscillator type to be used, which of the power-managed
modes to invoke and the output frequency of the
INTOSC source. It also provides status on the oscillators.

Control Registers
Reset state depends on the state of the IESO Configuration bit (CONFIG1H<7>).
Modifying these bits will cause an immediate clock frequency switch if the internal oscillator is providing
the device clocks.
Source selected by the INTSRC bit (OSCTUNE<7>).
Modifying these bits will cause an immediate clock source switch.
INTSRC = OSCTUNE<7> and MFIOSEL = OSCCON2<0>.
IDLEN: Idle Enable bit
1 = Device enters an Idle mode when a SLEEP instruction is executed
0 = Device enters Sleep mode when a SLEEP instruction is executed

OSTS
The OSCTUNE register (Register 3-3) controls the
tuning and operation of the internal oscillator block. It also
implements the PLLEN bit which controls the operation of
the Phase Locked Loop (PLL) (see Section 3.5.2 “PLL
Frequency Multiplier”).
