Timers And Counters

Tmod is an 8 bit register used for selecting timer or counter and mode of timers.

Timers and counters.

In arduino uno it takes 1 16000000 seconds or 62nano seconds to make a single count. Set a silent timer clock or choose a sound. 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. Both timer 0 and timer 1 are 16 bit wide.

Tmod timer mode register and tcon timer control register which are used for activating and configuring timers and counters. Create one or multiple timers and start them in any order. Lower 4 bits are used for control operation of timer. Use these products for monitoring quadrature encoders event counting period measurement pulse generation pulse train generation two edge separation measurement and more.

Meaning arduino moves from one instruction to another instruction for every 62 nano second. Timer online with alarm. 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.

They can be used as timers or as event counters. A timer uses counter which counts at certain speed depending upon the clock frequency. The 16 bit register of timer 0 is accessed as low and high byte. Timer mode control tmod.
