Dead-time generation may be provided when any of
the PWM I/O pin pairs are operating in the Comple-
mentary Output mode. The PWM outputs use Push-
Pull drive circuits. Due to the inability of the power out-
put devices to switch instantaneously, some amount of
time must be provided between the turn off event of one
PWM output in a complementary pair and the turn on
event of the other transistor.
The PWM module allows two different dead-times to be
programmed. These two dead-times may be used in
one of two methods described below to increase user
flexibility:
• The PWM output signals can be optimized for dif-
• The two dead-times can be assigned to individual

ferent turn off times in the high side and low side
transistors in a complementary pair of transistors.
The first dead-time is inserted between the turn
off event of the lower transistor of the complemen-
tary pair and the turn on event of the upper tran-
sistor. The second dead-time is inserted between
the turn off event of the upper transistor and the
turn on event of the lower transistor.
PWM I/O pin pairs. This Operating mode allows
the PWM module to drive different transistor/load
combinations with each complementary PWM I/O
pin pair.

Preliminary
15.7.1
Each complementary output pair for the PWM module
has a 6-bit down counter that is used to produce the
dead-time insertion. As shown in Figure 15-4, each
dead-time unit has a rising and falling edge detector
connected to the duty cycle comparison output.
15.7.2
The amount of dead-time provided by the dead-time
unit is selected by specifying the input clock prescaler
value and a 6-bit unsigned value.
Four input clock prescaler selections have been pro-
vided to allow a suitable range of dead-time, based on
the device operating frequency. The dead-time clock
prescaler values are selected using the DTAPS<1:0>
control bits in the DTCON1 SFR. One of four clock
prescaler options (T
selected.
After the prescaler value is selected, the dead-time is
adjusted by loading 6-bit unsigned values into the
DTCON1 SFR.
The dead-time unit prescaler is cleared on the following
events:
• On a load of the down timer due to a duty cycle
• On a write to the DTCON1 register.
• On any device Reset.
