MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -Timer Control Register (TCON): TCON is another register used to control operations of counter and timers in microcontrollers. It is an 8-bit register wherein four upper bits are responsible for timers and counters and lower bits are responsible for interrupts.

Detailed explanation-2: -TMOD (Timer Mode) Register It is an 8-bit register in which the lower 4 bits are set aside for Timer 0 and the upper four bits for Timers. In each case, the lower 2 bits are used to set the timer mode in advance and the upper 2 bits are used to specify the location.

Detailed explanation-3: -TMOD register is used to set different timer’s or counter’s to their appropriate modes so that it tells the user that what mode is being used when operating any timer or counter.
