LPC5411x
32-bit ARM Cortex-M4/M0+ microcontroller
Every action that the SCTimer/PWM block can perform occurs in direct response to one of
these user-defined events without any software overhead. Any event can be enabled to:
• Start, stop, or halt the counter.
• Limit the counter which means to clear the counter in unidirectional mode or change
its direction in bi-directional mode.
• Set, clear, or toggle any SCTimer/PWM output.
• Force a capture of the count value into any capture registers.
• Generate an interrupt of DMA request.
7.20.2.1 Features
• The SCTimer/PWM Supports:
– Eight inputs.
– Eight outputs.
– Ten match/capture registers.
– Ten events.
– Ten states.
• Counter/timer features:
– Each SCTimer/PWM is configurable as two 16-bit counters or one 32-bit counter.
– Counters clocked by system clock or selected input.
– Configurable number of match and capture registers. Up to five match and capture
registers total.
– Ten events.
– Ten states.
– Upon match and/or an input or output transition create the following events:
interrupt; stop, limit, halt the timer or change counting direction; toggle outputs;
change the state.
– Counter value can be loaded into capture register triggered by a match or
input/output toggle.
