Timers And Counters

Lower 4 bits are used for control operation of timer.

Timers and counters.

Set a silent timer clock or choose a sound. Meaning arduino moves from one instruction to another instruction for every 62 nano second. Tmod timer mode register and tcon timer control register which are used for activating and configuring timers and counters. A timer is an application of the counters where a certain signal with a fixed frequency hence period is counted to record the time.

The 8051 has two timers timer 0 and timer 1. Timer mode control tmod. A timer uses counter which counts at certain speed depending upon the clock frequency. Both timer 0 and timer 1 are 16 bit wide.

Use these products for monitoring quadrature encoders event counting period measurement pulse generation pulse train generation two edge separation measurement and more. Tmod is an 8 bit register used for selecting timer or counter and mode of timers. Since the 8051 follows an 8 bit architecture each 16 bit is accessed as two separate registers of low byte and high byte. Counters and timers provide timing and digital i o.

Create one or multiple timers and start them in any order. They can be used as timers or as event counters. In arduino uno it takes 1 16000000 seconds or 62nano seconds to make a single count. Timer online with alarm.
