To start or stop the timer TR flag is used.
Tl0 and th0 are linked with the timer0, they indicate the timer0 where to start its value
TL0/TL1= We wont to start the program in starting/middle/ending stages used TL0
THO/TH1=We wont to stop the program in starting/middle/ending stages used TH0
Tl0 and th0 are linked with the timer0, they indicate the timer0 where to start its value

THO/TH1=We wont to stop the program in starting/middle/ending stages used TH0

Either (TL0 / TH0) or (TL1 / TH1) is needed to start the timer. Because (TL0 / TH0) corresponding to Timer 0 and (TL1 / TH1) corresponding to Timer 1. We must able to use ONLY ONE TIMER AT A TIME.

To start timer 0 programmer needs to load values in TL0 and TH0 only. Hence answer is false because while dealing with Timer0 there is no role of TH1 or TL1.

TL0 is used for to start the timer 0 and TL1 is used for to start the timer 2 so both need not be set for to start the timer 0.

All the above answers are wrong.
For timer0 tl0/th0 are used. So this s the correct answer.

Timers opreated in 4 modes.
We use TLO&THO to operate TIMER0 IN those modes.

Because whenever we want to run timer the TR register we will run.
