LPC2927/2929

ARM9 microcontroller with CAN, LIN, and USB

control. Several other trigger possibilities are provided for the ADCs (external, cascaded

or following a PWM). The capture inputs of both timers can also be used to capture the

start pulse of the ADCs.

The PWMs can be used to generate waveforms in which the frequency, duty cycle and

rising and falling edges can be controlled very precisely. Capture inputs are provided to

measure event phases compared to the main counter. Depending on the applications,

these inputs can be connected to digital sensor motor outputs or digital external signals.

Interrupt signals are generated on several events to closely interact with the CPU.

The ADCs can be used for any application needing accurate digitized data from analog

sources. To support applications like motor control, a mechanism to synchronize several

PWMs and ADCs is available (sync_in and sync_out).

Note that the PWMs run on the PWM clock and the ADCs on the ADC clock, see

Section 6.16.2.
