MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -The 16-bit register of Timer 1 is accessed as low-and high-byte. The low-byte register is called TL1 (Timer 1 low byte) and the high-byte register is called TH1 (Timer 1 high byte).

Detailed explanation-2: -T0CON (Timer 0 Control) register is used to program the timer and includes the bits shown in figure (T0CS, PSA etc.) The clock source can be internal or external and is controlled by T0CS bit.

Detailed explanation-3: -T08BIT and TMR0ON are the bits which are used to determine bit mode of the timer(8 or 16) and to on/off the timer respectively. # Normally we feed the ADCON register with 00001000(08H). It bypasses prescaler frequency i.e. input frequency=OSC/4, use 16 bit mode and sets the timer for internal clock input.

Detailed explanation-4: -Which of the timer can operate in the 16 bit condition? Explanation: Timer0 and Timer2 can operate in the 8 bit condition while only Timer 1 operates in the 16 bit condition.
