Bits in tcon register
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. Web8051 has 5 interrupt signals, i.e. INT0, TFO, INT1, TF1, RI/TI. Each interrupt can be enabled or disabled by setting bits of the IE register and the whole interrupt system can be disabled by clearing the EA bit of the same register. IE (Interrupt Enable) Register. This register is responsible for enabling and disabling the interrupt.
