4. Module: Early Termination of Nested DO
EXAMPLE 4:

LOOP1: MOV
LOOP0: MOV
Note:
When using two DO loops in a nested fashion,
terminating the inner-level DO loop by setting the
EDT (CORCON<11>) bit will produce unexpected
results. Specifically, the device may continue
executing code within the outer DO loop forever.
This erratum does not affect the operation of the
MPLAB C30 compiler.
Work around
The application should save the DCOUNT SFR
prior to entering the inner DO loop and restore it
upon exiting the inner DO loop. This work around is
shown in Example 4.

5. Module: 4x PLL Operation
dsPIC30F3010/3011
When the 4x PLL mode of operation is selected,
the specified input frequency range of 4-10 MHz is
not fully supported.
When device V
frequency must be in the range of 4-5 MHz. When
device V
must be in the range of 4-6 MHz for both industrial
and extended temperature ranges.
Work around
1. Use 8x PLL or 16x PLL mode of operation and
2. Use the EC without PLL Clock mode with a
set final device clock speed using the
POST<1:0> oscillator postscaler control bits
(OSCCON<7:6>).

4x PLL clock rate.
