The following occur in Sleep mode:
• The system clock source is shut down. If an

• The Fail-Safe Clock Monitor does not operate,
• The LPRC clock continues to run in Sleep mode if
• The WDT, if enabled, is automatically cleared
• Some device features or peripherals can continue
• Any peripheral that requires the system clock
The device wakes up from Sleep mode on any of the
these events:
• Any interrupt source that is individually enabled
• Any form of device Reset
• A WDT time-out
On wake-up from Sleep mode, the processor restarts
with the same clock source that was active when Sleep
mode was entered.
For optimal power savings, the internal regulator and
the Flash regulator can be configured to go into Stand-
by when Sleep mode is entered by clearing the VREGS
(RCON<8>) and VREGSF (RCON<11>) bits (default
configuration).
If the application requires a faster wake-up time, and
can accept higher current requirements, the VREGS
(RCON<8>) and VREGSF (RCON<11>) bits can be set
to keep the internal regulator and the Flash regulator
active during Sleep mode.

The following occur in Idle mode:

The device wakes from Idle mode on any of these
events:
• Any interrupt that is individually enabled
• Any device Reset
• A WDT time-out
On wake-up from Idle mode, the clock is reapplied to
the CPU and instruction execution will begin (2-4 clock
cycles later), starting with the instruction following the
PWRSAV instruction, or the first instruction in the ISR.
All peripherals also have the option to discontinue
operation when Idle mode is entered to allow for
increased power savings. This option is selectable in
the control register of each peripheral. For example,
the TSIDL bit in the Timer1 Control register
(T1CON<13>).
10.2.3
Any interrupt that coincides with the execution of a
PWRSAV instruction is held off until entry into Sleep or
Idle mode has completed. The device then wakes up
from Sleep or Idle mode.
