7.19 Counter/timers and motor control
The LPC4350/30/20/10 include four 32-bit timer/counters. The timer/counter is designed
to count cycles of the system derived clock or an externally-supplied clock. It can
optionally generate interrupts, generate timed DMA requests, or perform other actions at
specified timer values, based on four match registers. Each timer/counter also includes
two capture inputs to trap the timer value when an input signal transitions, optionally
generating an interrupt.
The motor control PWM is a specialized PWM supporting 3-phase motors and other
combinations. Feedback inputs are provided to automatically sense rotor position and use
that information to ramp speed up or down. An abort input is also provided that causes the

Conforms to protocol version 2.0 parts A and B.
Supports bit rate of up to 1 Mbit/s.
Supports 32 Message Objects.
Each Message Object has its own identifier mask.
Provides programmable FIFO mode (concatenation of Message Objects).
Provides maskable interrupts.
Supports Disabled Automatic Retransmission (DAR) mode for time-triggered CAN
applications.
Provides programmable loop-back mode for self-test operation.
A 32-bit timer/counter with a programmable 32-bit prescaler.
Counter or timer operation.
Two 32-bit capture channels per timer, that can take a snapshot of the timer value
when an input signal transitions. A capture event may also generate an interrupt.
Four 32-bit match registers that 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.
Up to four external outputs corresponding to match registers, with the following
capabilities:
– Set LOW on match.
– Set HIGH on match.
– Toggle on match.
– Do nothing on match.
Up to two match registers can be used to generate timed DMA requests.
