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 15-5, each
dead-time unit has a rising and falling edge detector
connected to the duty cycle comparison output.
15.7.2
The DTCON2 SFR contains control bits that allow the
dead-times to be assigned to each of the complemen-
tary outputs. Table 15-2 summarizes the function of
each dead-time selection control bit.
TABLE 15-2:
FIGURE 15-5:
15.8
An independent PWM Output mode is required for driv-
ing certain types of loads. A particular PWM output pair
is in the Independent Output mode when the corre-
sponding PMOD bit in the PWMCON1 register is set.
No dead-time control is implemented between adjacent
PWM I/O pins when the module is operating in the
Independent mode and both I/O pins are allowed to be
active simultaneously.

Preliminary
15.7.3
The amount of dead-time provided by each dead-time
unit is selected by specifying the input clock prescaler
value and a 6-bit unsigned value. The amount of dead-
time provided by each unit may be set independently.
Four input clock prescaler selections have been pro-
vided to allow a suitable range of dead-times, based on
the device operating frequency. The clock prescaler
option may be selected independently for each of the
two dead-time values. The dead-time clock prescaler
values are selected using the DTAPS<1:0> and
DTBPS<1:0> control bits in the DTCON1 SFR. One of
four clock prescaler options (T
may be selected for each of the dead-time values.
After the prescaler values are selected, the dead-time
for each unit is adjusted by loading two 6-bit unsigned
values into the DTCON1 SFR.
The dead-time unit prescalers are cleared on the fol-
lowing events:
• On a load of the down timer due to a duty cycle
• On a write to the DTCON1 or DTCON2 registers.
• On any device Reset.
In the Independent mode, each duty cycle generator is
connected to both of the PWM I/O pins in an output
pair. By using the associated duty cycle register and
the appropriate bits in the OVDCON register, the user
may select the following signal output options for each
PWM I/O pin operating in the Independent mode:
• I/O pin outputs PWM signal
• I/O pin inactive
• I/O pin active
comparison edge event.
Note:
DEAD-TIME RANGES
The user should not modify the DTCON1
or DTCON2 values while the PWM mod-
ule is operating (PTEN = 1). Unexpected
results may occur.
