Any interrupt that is individually enabled (using the cor-
responding IE bit) and meets the prevailing priority level
can wake-up the processor. The processor processes
the interrupt and branch to the ISR. The SLEEP status
bit in the RCON register is set upon wake-up.
All Resets wake up the processor from Sleep mode.
Any Reset, other than POR, sets the Sleep status bit.
In a POR, the SLEEP bit is cleared.
If the Watchdog Timer is enabled, the processor wakes
up from Sleep mode upon WDT time-out. The SLEEP
and WDTO status bits are both set.
20.7.2
IDLE MODE
In Idle mode, the clock to the CPU is shut down while
peripherals keep running. Unlike Sleep mode, the clock
source remains active.
Several peripherals have a control bit in each module
that allows them to operate during Idle.
The LPRC fail-safe clock remains active if clock failure
detect is enabled.
The processor wakes up from Idle if at least one of the
following conditions has occurred:
any interrupt that is individually enabled (IE bit is
‘1’) and meets the required priority level
any Reset (POR, BOR, MCLR)
WDT time-out
Upon wake-up from Idle mode, the clock is re-applied
to the CPU and instruction execution begins immedi-
ately, starting with the instruction following the PWRSAV
instruction.
Any interrupt that is individually enabled (using the IE
bit) and meets the prevailing priority level is able to
wake up the processor. The processor processes the
interrupt and branches to the ISR. The IDLE status bit
in the RCON register is set upon wake-up.
Any Reset other than POR sets the IDLE status bit. On
a POR, the IDLE bit is cleared.
If Watchdog Timer is enabled, the processor wakes up
from Idle mode upon WDT time-out. The Idle and
WDTO status bits are both set.
Unlike wake-up from Sleep, there are no time delays
involved in wake-up from Idle.

Device Configuration Registers
The Configuration bits in each device Configuration
register specify some of the device modes and are
programmed by a device programmer, or by using the
In-Circuit Serial Programming (ICSP) feature of
the device. Each device Configuration register is a
24-bit register, but only the lower 16 bits of each regis-
ter are used to hold configuration data. There are five
device Configuration registers available to the user:
1.
FOSC (0xF80000): Oscillator Configuration
Register
2.
FWDT (0xF80002): Watchdog Timer
Configuration Register
3.
FBORPOR (0xF80004): BOR and POR
Configuration Register
4.
FGS (0xF8000A): General Code Segment
Configuration Register
5.
FICD (0xF8000C): Debug Configuration
Register
The placement of the Configuration bits is automati-
cally handled when you select the device in your device
programmer. The desired state of the Configuration bits
may be specified in the source code (dependent on the
language tool used), or through the programming
interface. After the device has been programmed, the
application software may read the Configuration bit
values through the table read instructions. For
additional information, please refer to the Programming
Specifications of the device.
Note:
In spite of various delays applied (TPOR,
TLOCK and TPWRT), the crystal oscillator
(and PLL) may not be active at the end of
the time-out (e.g., for low-frequency crys-
tals). In such cases, if FSCM is enabled, the
device detects this as a clock failure and
processes the clock failure trap, the FRC
oscillator is enabled and the user will have
to re-enable the crystal oscillator. If FSCM
is not enabled, the device simply suspends
execution of code until the clock is stable
and remain in Sleep until the oscillator clock
has started.
Note:
If the code protection Configuration fuse
bits
(FGS<GCP> and FGS<GWRP>)
have been programmed, an erase of the
entire
code-protected
device
is
only
possible at voltages VDD
4.5V.
