15.1.4
In the Double Update mode (PTMOD<1:0> = 11), an
interrupt event is generated each time the PTMR regis-
ter is equal to zero, as well as each time a period match
occurs. The postscaler selection bits have no effect in
this mode of the timer.
The Double Update mode provides two additional func-
tions to the user. First, the control loop bandwidth is
doubled because the PWM duty cycles can be
updated, twice per period. Second, asymmetrical
center-aligned PWM waveforms can be generated
which are useful for minimizing output waveform
distortion in certain motor control applications.
15.1.5
The input clock to PTMR (F
options of 1:1, 1:4, 1:16 or 1:64, selected by control
bits, PTCKPS<1:0>, in the PTCON SFR. The prescaler
counter is cleared when any of the following occurs:
• A write to the PTMR register
• A write to the PTCON register
• Any device Reset
The PTMR register is not cleared when PTCON is
written.
15.1.6
The match output of PTMR can optionally be post-
scaled through a 4-bit postscaler (which gives a 1:1 to
1:16 scaling).
The postscaler counter is cleared when any of the
following occurs:
• A write to the PTMR register
• A write to the PTCON register
• Any device Reset
The PTMR register is not cleared when the PTCON
register is written.

PTPER is a 15-bit register and is used to set the
counting period for the PWM time base. PTPER is a
double-buffered register. The PTPER buffer contents
are loaded into the PTPER register at the following
instants:
• Free-Running and Single-Shot modes: When the
• Continuous Up/Down Count modes: When the
The value held in the PTPER buffer is automatically
loaded into the PTPER register when the PWM time
base is disabled (PTEN = 0).
