DS80290J-page 6
None of the functions multiplexed on this pin yield
correct results.
As a result of this erratum, the following issues
exist:
• ADC channel AN7 does not produce the correct
• The comparator inputs, CMP3D and CMP4B,
• An external crystal is not supported as an
• The Clock Out function does not work
• RB7 cannot be used as a digital input or output
Work around
No work around is available for the OSC2 and
CLKO functionality. The AN7, CMP3D, CMP4B
and RB7 functions can be substituted by using
other available pins.
The data sheet indicates that the conversion rate
for the ADC module is 2.0 Msps. The ADC module
on the dsPIC30F1010/202X Rev. A1 silicon has a
maximum conversion rate of 1.5 Msps.
Work around
None.

10. Module: Current Reset Mode
Pin Number
Setting the XPRES bit in the PWMCONx register
should enable a current-limit source to reset the
PWM period in Independent Time Base mode.
This mode is not functioning correctly.
If the selected current-limit signal (either an analog
comparator or external signal) triggers after the
falling edge of PWMH, then the XPRES operation
functions correctly. The PWM deasserted time is
truncated and the PWM period is terminated early,
and a new PWM cycle begins.
If the selected current-limit signal (either an analog
comparator or external signal) triggers before the
falling edge of PWMH, the PWMH asserted time is
truncated, and the inactive time after the falling
edge PWMH remains constant.
The proper XPRES behavior is to ignore the
current-limit signal until the falling edge of the
PWM period.
This issue may not be a problem in applications
that control inductor current above a specified
minimum current level. When the inductor current
falls below the specified minimum value during the
PWMH off-time, the PWM period is truncated and
a new cycle begins to increase the inductor
current.
Work around
None.
