4.5
An exit from Sleep mode or any of the Idle modes is
triggered by an interrupt, a Reset or a WDT time-out.
This section discusses the triggers that cause exits
from power-managed modes. The clocking subsystem
actions are discussed in each of the power-managed
modes (see
Section 4.4 “Idle
4.5.1
Any of the available interrupt sources can cause the
device to exit from an Idle or Sleep mode to a Run
mode. To enable this functionality, an interrupt source
must be enabled by setting its enable bit in one of the
INTCON or PIE registers. The exit sequence is initiated
when the corresponding interrupt flag bit is set.
On all exits from Idle or Sleep modes by interrupt, code
execution branches to the interrupt vector if the
GIE/GIEH bit (INTCON<7>) is set. Otherwise, code
execution continues or resumes without branching
(see
A fixed delay of interval, T
event, is required when leaving Sleep and Idle modes.
This delay is required for the CPU to prepare for execu-
tion. Instruction execution resumes on the first clock
cycle following this delay.
4.5.2
A WDT time-out will cause different actions depending
on which power-managed mode the device is in when
the time-out occurs.
If the device is not executing code (all Idle modes and
Sleep mode), the time-out will result in an exit from the
power-managed

is executing code (all Run modes), the time-out will
result in a WDT Reset (see Section 24.2 “Watchdog
Timer (WDT)”).
The WDT timer and postscaler are cleared by execut-
ing a SLEEP or CLRWDT instruction, losing a currently
selected clock source (if the Fail-Safe Clock Monitor is
enabled) and modifying the IRCF bits in the OSCCON
register if the internal oscillator block is the device clock
source.

4.5.3
Normally, the device is held in Reset by the Oscillator
Start-up Timer (OST) until the primary clock becomes
ready. At that time, the OSTS bit is set and the device
begins executing code. If the internal oscillator block is
the new clock source, the IOFS bit is set instead.
The exit delay time from Reset to the start of code
execution depends on both the clock sources before
and after the wake-up and the type of oscillator if the
new clock source is the primary clock. Exit delays are
summarized in
Code execution can begin before the primary clock
becomes ready. If either the Two-Speed Start-up (see
Section 24.3 “Two-Speed Start-up”) or Fail-Safe
Clock Monitor (see Section 24.4 “Fail-Safe Clock
Monitor”) is enabled, the device may begin execution
as soon as the Reset source has cleared. Execution is
clocked by the INTOSC multiplexer driven by the
internal oscillator block. Execution is clocked by the
internal oscillator block until either the primary clock
becomes ready, or a power-managed mode is entered
before the primary clock becomes ready; the primary
clock is then shut down.
4.5.4
Certain exits from power-managed modes do not
invoke the OST at all. There are two cases:
• PRI_IDLE mode, where the primary clock source
• the primary clock source is not any of the LP, XT,
In these instances, the primary clock source either
does not require an oscillator start-up delay since it is
already running (PRI_IDLE), or normally does not
require an oscillator start-up delay (RC, EC and INTIO
Oscillator modes). However, a fixed delay of interval,
