14.11 PWM Output and Polarity Control
There are three device Configuration bits associated
with the PWM module that provide PWM output pin
control defined in the CONFIG3L register. They are:
• HPOL
• LPOL
• PWMPIN
These three Configuration bits work in conjunction with
the three PWM Enable bits (PWMEN2:PWMEN0) in
the PWMCON0 register. The Configuration bits and
PWM enable bits ensure that the PWM pins are in the
correct states after a device Reset occurs.
14.11.1
The PWMEN2:PWMEN0 control bits enable each
PWM output pin as required in the application.
All PWM I/O pins are general purpose I/O. When a pair
of pins is enabled for PWM output, the PORT and TRIS
registers controlling the pins are disabled. Refer to
Figure 14-23 for details.
14.11.2
The polarity of the PWM I/O pins is set during device
programming via the HPOL and LPOL Configuration
bits in the CONFIG3L register. The HPOL Configura-
tion bit sets the output polarity for the high side PWM
outputs: PWM1, PWM3 and PWM5. The polarity is
active-high when HPOL is set (= 1) and active-low
when it is cleared (= 0).
The LPOL Configuration bit sets the output polarity for
the low side PWM outputs: PWM0, PWM2 and PWM4.
As with HPOL, they are active-high when LPOL is set
and active-low when cleared.
All output signals generated by the PWM module are
referenced to the polarity control bits, including those
generated by Fault inputs or manual override (see
Section 14.10 “PWM Output Override”).
The default polarity Configuration bits have the PWM
I/O pins in active-high output polarity.
