TABLE 3-2:
3.2
The power-managed Sleep mode in the PIC18F2X20/
4X20 devices is identical to that offered in all other PIC
microcontrollers. It is entered by clearing the IDLEN
and SCS1:SCS0 bits (this is the Reset state) and
executing the SLEEP instruction. This shuts down the
primary oscillator and the OSTS bit is cleared (see
Figure 3-1).
When a wake event occurs in Sleep mode (by interrupt,
Reset or WDT time-out), the system will not be clocked
until the primary clock source becomes ready (see
Figure 3-2), or it will be clocked from the internal
oscillator block if either the Two-Speed Start-up or the
Fail-Safe Clock Monitor are enabled (see Section 23.0
“Special Features of the CPU”). In either case, the
OSTS bit is set when the primary clock is providing the
system clocks. The IDLEN and SCS bits are not
affected by the wake-up.
3.3
The IDLEN bit allows the controller’s CPU to be
selectively shut down while the peripherals continue to
operate. Clearing IDLEN allows the CPU to be clocked.
Setting IDLEN disables clocks to the CPU, effectively
stopping program execution (see Register 2-3). The
peripherals continue to be clocked regardless of the
setting of the IDLEN bit.

There is one exception to how the IDLEN bit functions.
When all the low-power OSCCON bits are cleared
(IDLEN:SCS1:SCS0 = 000), the device enters Sleep
mode upon the execution of the SLEEP instruction. This
is both the Reset state of the OSCCON register and the
setting that selects Sleep mode. This maintains
compatibility with other PIC devices that do not offer
power-managed modes.
If the Idle Enable bit, IDLEN (OSCCON<7>), is set to a
‘1’ when a SLEEP instruction is executed, the
peripherals will be clocked from the clock source
selected using the SCS1:SCS0 bits; however, the CPU
will not be clocked. Since the CPU is not executing
instructions, the only exits from any of the Idle modes
are by interrupt, WDT time-out or a Reset.
When a wake-up event occurs, CPU execution is
delayed approximately 10 μs while it becomes ready to
execute code. When the CPU begins executing code,
it is clocked by the same clock source as was selected
in the power-managed mode (i.e., when waking from
RC_IDLE mode, the internal oscillator block will clock
the CPU and peripherals until the primary clock source
becomes ready – this is essentially RC_RUN mode).
This continues until the primary clock source becomes
ready. When the primary clock becomes ready, the
OSTS bit is set and the system clock source is
switched to the primary clock (see Figure 3-4). The
IDLEN and SCS bits are not affected by the wake-up.
While in any Idle mode or Sleep mode, a WDT time-out will
result in a WDT wake-up to full-power operation.
