3.3
The power-managed Sleep mode is identical to the
legacy Sleep mode offered in all other PIC devices. It is
entered by clearing the IDLEN bit (the default state on
device Reset) and executing the SLEEP instruction.
This shuts down the selected oscillator (Figure 3-5). All
clock source status bits are cleared.
Entering the Sleep mode from any other mode does not
require a clock switch. This is because no clocks are
needed once the controller has entered Sleep mode. If
the WDT is selected, the INTRC source will continue to
operate. If the Timer1 oscillator is enabled, it will also
continue to run.

PIC18F46J11 FAMILY
When a wake event occurs in Sleep mode (by interrupt,
Reset or WDT time-out), the device will not be clocked
until the clock source selected by the SCS<1:0> bits
becomes ready (see Figure 3-6), or it will be clocked
from the internal oscillator if either the Two-Speed
Start-up or the FSCM is enabled (see Section 25.0
“Special Features of the CPU”). In either case, the
OSTS bit is set when the primary clock is providing the
device clocks. The IDLEN and SCS bits are not
affected by the wake-up.
