edge controlled PWM outputs require only one match register each, since the
repetition rate is the same for all PWM outputs. Multiple single edge controlled PWM
outputs will all have a rising edge at the beginning of each PWM cycle, when an MR0
match occurs.
Three match registers can be used to provide a PWM output with both edges
controlled. Again, the MR0 match register controls the PWM cycle rate. The other
match registers control the two PWM edge positions. Additional double edge
controlled PWM outputs require only two match registers each, since the repetition
rate is the same for all PWM outputs.
With double edge controlled PWM outputs, specific match registers control the rising
and falling edge of the output. This allows both positive going PWM pulses (when the
rising edge occurs prior to the falling edge), and negative going PWM pulses (when
the falling edge occurs prior to the rising edge).

Features
Seven match registers allow up to six single edge controlled or three double edge
controlled PWM outputs, or a mix of both types.
The match registers also allow:
–
Continuous operation with optional interrupt generation on match.
–
Stop timer on match with optional interrupt generation.
–
Reset timer on match with optional interrupt generation.
Supports single edge controlled and/or double edge controlled PWM outputs.
Single edge controlled PWM outputs all go HIGH at the beginning of each cycle
unless the output is a constant LOW. Double edge controlled PWM outputs can
have either edge occur at any position within a cycle. This allows for both positive
going and negative going pulses.
Pulse period and width can be any number of timer counts. This allows complete
flexibility in the trade-off between resolution and repetition rate. All PWM outputs
will occur at the same repetition rate.
Double edge controlled PWM outputs can be programmed to be either positive
going or negative going pulses.
Match register updates are synchronized with pulse outputs to prevent generation
of erroneous pulses. Software must “release” new match values before they can
become effective.
May be used as a standard timer if the PWM mode is not enabled.
