Two programmable interval timers were available, each with sub-microsecond precision.

A real-time clock is incorporated in the CIA, providing a timekeeping device more conducive to human needs than the microsecond precision of the interval timers.

(Other names include interval meter and interval timer).

A preemptive scheduler relies upon a programmable interval timer which invokes an interrupt handler that runs in kernel Mode and implements the scheduling function.

The TED includes three 16-bit interval timers, which consist of down counters operating at the master clock frequency.

The release in 1978 of the Programmable interval timer by Intel was significant.

Also, using either of the motor drive systems also enables use of electronic interval timers and remote shutter releases, both wired and wireless.

The DAI also had five programmable interval 64 - 16ms interval timers that could generate interrupts.

A PC speaker generates waveforms using the programmable interval timer.

The clock rate of the PC's programmable interval timer which drives the speaker is fixed at 1,193.18 kHz.
