User manual
A sample of how PWM values relate to waveform outputs is shown in
PWM output logic is shown in
double edge controlled PWM outputs via the muxes controlled by the PWMSELn bits. The
match register selections for various PWM outputs is shown in
implementation of the PWM module supports up to N-1 single edge PWM outputs or
(N-1)/2 double edge PWM outputs, where N is the number of match registers that are
implemented. PWM types can be mixed if desired.For LPC2400 devices N = 7 which
gives up to 6 single edge PWM outputs or up to 3 double edge PWM outputs available at
the same time
5. The maximum number of match registers is increased to 7 in order to allow support
6. Add PWM outputs to the timer that connect a functional equivalent of an RS Flip-Flop
7. Three interrupt bits are added to the IR register.
Fig 133. Sample PWM waveforms
for up to 3 double edge PWM channels. This includes the necessary match outputs,
control bits, etc. for each match register:
– Three new Match registers are added, creating Match channels 4 through 6.
– Three additional sets of stop (S), reset (R), and interrupt (I) bits are added to the
to two match outputs. A 2-to-1 mux on each PWM output allows selection of either a
single or a double edged PWM. A new register (PCR) is added to hold the control bits
for the muxes (PWMSEL bits).
MCR register (3 per additional match register).
The waveforms below show a single PWM cycle and demonstrate PWM outputs under the
following conditions:
The timer is configured for PWM mode (counter resets to one).
Match 0 is configured to reset the timer/counter when a match event occurs.
Control bits PWMSEL2 and PWMSEL4 are set.
The Match register values are as follows:
MR0 = 100 (PWM rate)
MR1 = 41, MR2 = 78 (PWM2 output)
MR3 = 53, MR4 = 27 (PWM4 output)
MR5 = 65 (PWM5 output)
