17.8.2
PWM output may be manually overridden for each
PWM channel by using the appropriate bits in the
OVDCOND and OVDCONS registers. The user may
select the following signal output options for each PWM
output pin operating in the Independent PWM mode:
• I/O pin outputs PWM signal
• I/O pin inactive
• I/O pin active
Refer to Section 17.10 “PWM Output Override” for
details for all the override functions.
FIGURE 17-19:

The single-pulse PWM operation is available only in
Edge-Aligned mode. In this mode, the PWM module
will
operation is configured when the PTMOD1:PTMOD0
bits are set to ‘01’ in the PTCON0 register. This mode
of operation is useful for driving certain types of ECMs.
In Single-Pulse mode, the PWM I/O pin(s) are driven to
the active state when the PTEN bit is set. When the
PWM timer match with the Duty Cycle register occurs,
the PWM I/O pin is driven to the inactive state. When
the PWM timer match with the PTPER register occurs,
the PTMR register is cleared, all active PWM I/O pins
are driven to the inactive state, the PTEN bit is cleared
and an interrupt is generated if the corresponding
interrupt bit is set.
17.10 PWM Output Override
The PWM output override bits allow the user to manu-
ally drive the PWM I/O pins to specified logic states,
independent of the duty cycle comparison units. The
PWM override bits are useful when controlling various
types of ECMs like a BLDC motor.

Preliminary
OVDCOND and OVDCONS registers are used to
define the PWM override options. The OVDCOND
register contains eight bits, POVD7:POVD0, that
determine which PWM I/O pins will be overridden. The
OVDCONS
POUT7:POUT0, that determine the state of the PWM
I/O pins when a particular output is overridden via the
POVD bits.
The POVD bits are active-low control bits. When the
POVD bits are set, the corresponding POUT bit will
have no effect on the PWM output. In other words, the
pins corresponding to POVD bits that are set will have
the duty PWM cycle set by the PDCx registers. When
one of the POVD bits is cleared, the output on the cor-
responding PWM I/O pin will be determined by the
state of the POUT bit. When a POUT bit is set, the
PWM pin will be driven to its active state. When the
POUT bit is cleared, the PWM pin will be driven to its
inactive state.
17.10.1
The even numbered PWM I/O pins have override
restrictions when a pair of PWM I/O pins are operating
in the Complementary mode (PMODx = 0). In Comple-
mentary mode, if the even numbered pin is driven
active by clearing the corresponding POVD bit and by
setting POUT bits in the OVDCOND and OVDCONS
registers, the output signal is forced to be the comple-
ment of the odd numbered I/O pin in the pair (see
Figure 17-2 for details).
17.10.2
If the OSYNC bit in the PWMCON1 register is set, all
output overrides performed via the OVDCOND and
OVDCONS registers will be synchronized to the PWM
time base. Synchronous output overrides will occur on
the following conditions:
• When the PWM is in Edge-Aligned mode,
• When the PWM is in Center-Aligned mode,
synchronization occurs when PTMR is zero.
synchronization occurs when PTMR is zero and
when the value of PTMR matches PTPER.
