WebTimer 0 and timer 1 are two timer registers in 8051. Both of these registers use the same register called TMOD to set various timer operation modes. TMOD is an 8-bit register. The lower 4 bits are for Timer 0. The upper 4 bits are for Timer 1. In each case, The lower 2 bits are used to set the timer mode. WebTCON. TCON register is also one of the registers whose bits are directly in control of timer operation. The 4 bits in LSB is used for interrupt control. TF1 bit is automatically set when the Timer 1 overflow. TR1 bit enables …
