User manual
The Timer/Counter is designed to count cycles of the peripheral clock (PCLK) or an
externally-supplied clock, and can optionally generate interrupts or perform other actions
at specified timer values, based on four match registers. It also includes four capture
inputs to trap the timer value when an input signal transitions, optionally generating an
interrupt.
Remark: The capture inputs are shared between four SCT inputs and the timer inputs.
The timer match outputs are ORed with the SCT outputs (see

Counter or Timer operation
Up to four 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 optionally 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.
