timers can generate an interrupt on overflow.

Except for usage as baud rate generators the timers mostly used to generate an interrupt, e.g.:

- to read and debouncing keys,
- to drive multiplexed displays,
- to drive a speaker
- to flash LEDs
- to count up the RTC,
- to measure pulse length, e.g. of IR signals,
- to implement additional software UARTs
and so on.
