19.1.3
The power-managed mode that is invoked with the
SLEEP instruction is determined by the setting of the
IDLEN bit of the OSCCON register at the time the
instruction is executed. All clocks stop and minimum
power is consumed when SLEEP is executed with the
IDLEN bit cleared. The system clock continues to sup-
ply a clock to the peripherals but is disconnected from
the CPU when SLEEP is executed with the IDLEN bit
set.
19.2
In the Run modes, clocks to both the core and
peripherals are active. The difference between these
modes is the clock source.
19.2.1
The PRI_RUN mode is the normal, full power execution
mode of the microcontroller. This is also the default
mode upon a device Reset, unless Two-Speed Start-up
is enabled (see

off the oscillator defined by the FOSC bits of the
CONFIGH Configuration register.
19.2.2
In SEC_RUN mode, the CPU and peripherals are
clocked from the secondary external oscillator. This
gives users the option of lower power consumption
while still using a high accuracy clock source.
SEC_RUN mode is entered by setting the SCS<1:0>
bits of the OSCCON register to ‘01’. When SEC_RUN
mode is active all of the following are true:
• The main clock source is switched to the
• Primary external oscillator is shut down
• T1RUN bit of the T1CON register is set
• OSTS bit is cleared.

SEC_RUN MODE
The secondary external oscillator should
already be running prior to entering
SEC_RUN mode. If the T1OSCEN bit is
not set when the SCS<1:0> bits are set to
‘01’, entry to SEC_RUN mode will not
occur until T1OSCEN bit is set and sec-
ondary external oscillator is ready.

19.2.3
In RC_RUN mode, the CPU and peripherals are
clocked from the internal oscillator. In this mode, the
primary external oscillator is shut down. RC_RUN
mode provides the best power conservation of all the
Run modes when the LFINTOSC is the system clock.
RC_RUN mode is entered by setting the SCS1 bit.
When the clock source is switched from the primary
oscillator to the internal oscillator, the primary oscillator
is shut down and the OSTS bit is cleared. The IRCF bits
may be modified at any time to immediately change the
clock speed.
