MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -The Timer0 module can be used as an 8-bit timer. In timer mode, it is incremented on every instruction clock pulse unless a prescaler is used to reduce the speed. The TMR0 register can be written via software to preload it with a value.

Detailed explanation-2: -Both Timer 0 and Timer 1 are 16-bit wide. Since the 8051 follows an 8-bit architecture, each 16 bit is accessed as two separate registers of low-byte and high-byte.

Detailed explanation-3: -8-bit Timers can only count up to 255.

Detailed explanation-4: -The 8-bit timer is a general-purpose counter module, it includes a bidirectional counter, an interruption generation block, input pulse and external clock count modes, provides PWM (Pulse Width Modulation) and trigger pulse events.

Detailed explanation-5: -Timer 0 Registers Timer 0 has a register called TMR0 Register, which is 8 bits of size. The below table shows the registers associated with PIC16f877A Timer 0 module.
