F.4 PWM Outputs
The Pulse-Width Modulator consists of a 10-bit free-running counter and four width regis-
ters. Each PWM output is high for
n
+ 1 counts out of the 1024-clock count cycle, where
n
is the value held in the width register. The PWM output high time can optionally be spread
throughout the cycle to reduce ripple on the externally filtered PWM output. The PWM is
clocked by the output of Timer A9. The spreading function is implemented by dividing
each 1024-clock cycle into four quadrants of 256 clocks each. Within each quadrant, the
Pulse-Width Modulator uses the eight MSBs of each pulse-width register to select the base
width in each of the quadrants. This is the equivalent to dividing the contents of the pulse-
width register by four and using this value in each quadrant. To get the exact high time, the
Pulse-Width Modulator uses the two LSBs of the pulse-width register to modify the high
time in each quadrant according to Table F-3 below. The “
n
/4” term is the base count, and
is formed from the eight MSBs of the pulse-width register.
The diagram below shows a PWM output for several different width values for both
modes of operation. Operation in the spread mode reduces the filtering requirements on
the PWM output in most cases.
