Timers And Counters

Both timer 0 and timer 1 are 16 bit wide.

Timers and counters.

Lower 4 bits are used for control operation of timer. Tmod is an 8 bit register used for selecting timer or counter and mode of timers. Tmod timer mode register and tcon timer control register which are used for activating and configuring timers and counters. Set a silent timer clock or choose a sound.

The 8051 has two timers timer 0 and timer 1. In arduino uno it takes 1 16000000 seconds or 62nano seconds to make a single count. A timer uses counter which counts at certain speed depending upon the clock frequency. A timer is an application of the counters where a certain signal with a fixed frequency hence period is counted to record the time.

Timer mode control tmod. Counters and timers provide timing and digital i o. Meaning arduino moves from one instruction to another instruction for every 62 nano second. Timer online with alarm.

They can be used as timers or as event counters. Since the 8051 follows an 8 bit architecture each 16 bit is accessed as two separate registers of low byte and high byte. In modern applications counters are based on electronic devices and the counters are sequential logic circuit designed to record the number of electric pulses fed into the counter. The 16 bit register of timer 0 is accessed as low and high byte.
