Explanation:
Detailed explanation-1: -Microcontroller 8051 has two 16-bit timers and counters i.e. timer 0 and timer 1. Both timers consist of a 16-bit register in which the lower byte is stored in TL and the higher byte is stored in TH.
Detailed explanation-2: -8051 has two timers Timer0 (T0) and Timer1 (T1), both are 16-bit wide. Since 8051 has 8-bit architecture, each of these is accessed by two separate 8-bit registers as shown in the figure below. These registers are used to load timer count.
Detailed explanation-3: -This means that there are 3 sets of timers, each with the ability to count at different rates. The two 8-bit counters can count to 255 whilst the 16-bit counter can count to 65, 536.
