что имеется ввиду? FEATURES
• A 32-bit Timer/Counter with a programmable 32-bit Prescaler.
• 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.
APPLICATIONS
• Interval Timer for counting internal events.
• Pulse Width Demodulator via Capture inputs.
• Free running timer.
