8051 has Two Timer (each has 16 bit ) i am taking here Timer 0 It has to part First 8 bit (TL)) and the second part is (TH0) .
This timer is using to store the Pulses from the external (ie it will increment up to 65535 or FFFF)
TH0 = 0; // that timer clearing
TR0 = 1 // TR0 setting to start the counting .
