18.9.2
In Idle mode, the clock to the CPU is shutdown 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.
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 is true:
• on any interrupt that is individually enabled (IE bit
• on any Reset (POR, MCLR)
• on WDT time-out
Upon wake-up from Idle mode, the clock is reapplied to
the CPU and instruction execution begins immediately,
starting with the instruction following the PWRSAV
instruction.
Any interrupt that is individually enabled (using IE bit)
and meets the prevailing priority level will be able to
wake-up the processor. The processor will process the
interrupt and branch to the ISR. The Idle status bit in
RCON register is set upon wake-up.
Any Reset, other than POR, will set the Idle status bit.
On a POR, the Idle bit is cleared.
If Watchdog Timer is enabled, then the processor will
wake-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.

18.10 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 register are
used to hold configuration data. There are six
Configuration registers available to the user:
1.
2.
3.
4.
5.
6.
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 addi-
tional information, please refer to the programming
specifications of the device.
Table 18-5 shows the bit descriptions of the FGS and
FBS registers for the dsPIC30F1010. Table 18-6
shows the bit descriptions of the FGS and FBS regis-
ters for dsPIC30F202x devices. Table 18-7 shows the
bit descriptions of FWDT and the FPOR registers for
dsPIC30F1010/202X devices.
