19. Module: Motor Control PWM – Output
20. Module: Motor Control PWM – Dead Time
DS80195H-page 10
Unexpected results may occur when the PWM
pins are manually controlled using the OVDCON
register and the OSYNC bit (PWMCON2<1>) is
set.
Work around
Set OSYNC = 0 when the PWM pins are manually
controlled using the OVDCON register.
If the motor control PWM module is operated in
Complementary mode with a non-zero dead time,
unexpected results may occur on the PWM output
pins when the PWM pulse widths are less than or
equal to the programmed dead time.
Work around
The maximum and minimum duty cycles should be
limited in software so that the PWM pulse-width on
either complementary output pin is not equal to or
less than the dead time. If the PWM is used to
drive a motor or similar inductive load, the PWM
pulse-width on either complementary output pin
should be not less than three times the dead time
to avoid distortion of the load current. For pulse
widths less than the dead time, the PWM outputs
can be saturated to 0% or 100% duty cycle by
manual override of the PWM pins.

21. Module: CAN – Read Operations on SFRs
EXAMPLE 10:
Data read from the CAN module Special Function
Registers (SFRs) may not be correct at device
operation greater than 20 MIPS for V
range 4.75V to 5.5V (or 10 MIPS for V
range 3V to 3.6V).
If the dsPIC DSC 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 10. 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.
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 SFRs.
