Chapter 25: LPC24XX Pulse Width Modulator PWM0/PWM1
Rev. 04 — 26 August 2009
Remark: On reset, the both PWMs are enabled (PCPWM0/1 = 1).
Section
(Table
the VICIntEnable register
Two PWMs with the same operational features. The PWMs may be operated in a
synchronized fashion by setting them both up to run at the same rate, then enabling
both simultaneously. PWM0 acts as the Master and PWM1 as the slave for this use.
Counter or Timer operation (may use the peripheral clock or one of the capture inputs
as the clock source).
Seven match registers allow up to 6 single edge controlled or 3 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.
A 32 bit Timer/Counter with a programmable 32 bit Prescaler.
Three 32 bit capture channels take a snapshot of the timer value when an input signal
transitions. A capture event may also optionally generate an interrupt.
