16. Module: DCI
17. Module: CAN
EXAMPLE 12:
© 2010 Microchip Technology Inc.
For this release of silicon, the DCI module should
not be stopped when the device enters Idle mode.
Work around
Do not set the DCISIDL bit (DCICON1<13>). This
will ensure the DCI module continues to run when
the device enters Idle mode.
Affected Silicon Revisions
Data read from the CAN module Special Function
Registers may not be correct at device operation
greater than 20 MIPS for V
to 5.5V (or 10 MIPS for V
3.6V).
If the dsPIC DSC device needs to operate at a
throughput higher than 20 MIPS, the user should
incorporate the suggested work arounds while
reading CAN SFRs.
Applications that use Microchip’s dsPIC30F
Peripheral
CANbedded software, should operate the device
at 20 MIPS or less.
Work arounds
Work around 1: For Assembly Language
Source Code
When reading any CAN SFR, perform two
consecutive read operations of that SFR. The work
around is demonstrated in Example 12. In this
example, a Memory-Direct Addressing mode is
used to read the SFR. The application may use
any addressing mode to perform the read
operation. Note that interrupts must be disabled so
that the two consecutive reads do not get
interrupted.

18. Module: Flash Memory
Work around 2: For C Language Source Code
For C programmers, the MPLAB C30 v1.20.02
toolsuite provides a built-in function that may be
incorporated in the application source code. This
function may be used to read any CAN module
SFRs. Some examples of usage are shown in the
“readme.txt” file provided with the MPLAB C30
v1.20.02 toolsuite. The function has the following
prototype:
unsigned __builtin_readsfr(volatile void *);
The function argument is the address of a 16-bit
SFR. This function should only be used to read the
CAN Special Function Registers.
Affected Silicon Revisions
This release of silicon draws a current (I
approximately 370 mA during any Row Erase
operation performed on program Flash memory.
Work arounds
Work around 1:
Supply the V
capable of sourcing a minimum of 300 mA of
current.
Work around 2:
When using a voltage regulator capable of driving
150 mA current and if Brown-out Reset (BOR) is
enabled for a V
then connect a 1000 μF Electrolytic capacitor
across the V
If the Row Erase operation is performed as part of
a RTSP operation, the user should ensure that the
device is operating at less than 10 MIPS prior to
the erase operation. To ensure that the device is
operating at less than 10 MIPS, the application
may post-scale the system clock or switch to the
internal FRC oscillator.
