The PxDTCON2 SFR contains control bits that allow
the dead times to be assigned to each of the comple-
mentary outputs. Table 14-1 summarizes the function
of each dead-time selection control bit.

Preliminary
14.9.3
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 can 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 can 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 PxDTCON1 SFR. One
of four clock prescaler options (T

After the prescaler values are selected, the dead time
for each unit is adjusted by loading two 6-bit unsigned
values into the PxDTCON1 SFR.
The dead-time unit prescalers are cleared on the
following events:
• On a load of the down timer due to a duty cycle
• On a write to the PxDTCON1 or PxDTCON2
• On any device Reset.

DEAD-TIME RANGES
The user application should not modify the
PxDTCON1 or PxDTCON2 values while
the PWM module is operating (PTEN = 1).
Unexpected results can occur.
