2.7.1
The OSCCON register (Register 2-2) controls several
aspects of the device clock’s operation, both in full
power operation and in power-managed modes.
The System Clock Select bits, SCS1:SCS0, select the
clock source. The available clock sources are the
primary clock (defined by the FOSC2:FOSC0 Configu-
ration bits), the secondary clock (Timer1 oscillator) and
the internal oscillator. The clock source changes after
one or more of the bits are changed, following a brief
clock transition interval.
The OSTS (OSCCON<3>) and T1RUN (T1CON<6>)
bits indicate which clock source is currently providing
the device clock. The T1RUN bit indicates when the
Timer1 oscillator is providing the device clock in
secondary clock modes. In power-managed modes,
only one of these bits will be set at any time. If neither
bit is set, the INTRC source is providing the clock, or
the internal oscillator has just started and is not yet
stable.

OSTS
The IDLEN bit determines if the device goes into Sleep
mode or one of the Idle modes when the SLEEP
instruction is executed.
The use of the flag and control bits in the OSCCON
register is discussed in more detail in Section 3.0
“Power-Managed Modes”.

Timer1 oscillator is enabled by setting the

is not enabled, then any attempt to select
a secondary clock source will be ignored.
