REGISTER 17-5:
17.7.2
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 defined in the DTCON
register. Four input clock prescaler selections have
been provided to allow a suitable range of dead times
based on the device operating frequency. F
F
options available using the DTPS1:DTPS0 control bits
in the DTCON register.
After selecting an appropriate prescaler value, the
dead time is adjusted by loading a 6-bit unsigned value
into DTCON<5:0>. The dead-time unit prescaler is
cleared on any of the following events:
• On a load of the down timer due to a duty cycle
• On a write to the DTCON register; or
• On any device Reset.

The dead-time counter is clocked from any of the Q

The dead-time counter is clocked on Q1 when:
• The DTPS bits are set to any of the following
• The PWM Time Base Prescale bits
The dead-time counter is clocked by a pair of Q
clocks when the PWM Time Base Prescale bits
are set to 1:1 (PTCKPS1:PTCKPS0 = 00,

The dead-time counter is clocked using every
other Q clock, depending on the two LSbs in the
Duty Cycle registers:
• If the PWM duty cycle match occurs on Q1 or
• If the PWM duty cycle match occurs on Q2 or
When the DTPS1:DTPS0 bits are set to any of
the other dead-time prescaler settings (i.e.,
