What value do we need to load the timer’s register if we want to have a time delay of 5 ms (milliseconds) using timer 0, T0 in mode 1? Consider crystal frequency to be 12 MHz.1 pointTH0 = CEH, TL0 = 70HTL0 = ECH, TH0 = 78Hnone of theseTH0 = ECH, TL0 = 78H

f the crystal frequency is 4.5 MHz, determine the time for setting the timer flag for mode 1 if TH0 starts at 00H.1 point12 ms2 ms174.78 ms50 ms
