A timer is a simple counter! The input clock of microcontroller and operation of the timer is independent of the program execution.All the Atmel microcontrollers have Timers as an inbuilt peripheral.

The accumulator-based ST6 with only 40 instructions is a low-end µC with two 8-bit index registers; two 8-bit, general-purpose registers; an 8-bit accumulator register; and a 12-bit program counter.

A program counter can be made from a shift register and a half adder. This adds one to the total each time – and this was frequently used on bit serial CPUs – to keep the transistor/vacuum ...

It is an 8-bit STM8 Core device which is designed for high code efficiency. It contains six internal registers, 20 addressing modes and 80 instructions. The internal registers include two 16-bit Index ...
