The delay produced by 8051 Mode 1 timer with TH=20 and TL=0F, crystal frequency 11.0592MHz is*4 pointsA) 5.183 millisecondsB) 62.201 millisecondsC) 60.201 millisecondsD) 52.38 milliseconds

The 8051 microcontroller timer operates in four modes, and Mode 1 is a 16-bit timer mode. This means it uses both Timer High (TH) and Timer Low (TL) registers, each of which can hold a value from 00 to FF in hexadecimal, giving a range from 0000 to FFFF (or 0 to 65535 in decimal).

The timer counts up from the value loaded into TH and TL, to FFFF. When it rolls over from FFFF to 0000, it sets the Timer Flag (TF) and then reloads the original value from TH and TL and continues counting.

The time delay generated by the timer is determined by the crystal frequency and the initial values loaded into TH and TL.

Given:

• TH = 20 (hexadecimal) = 32 (decimal)
• TL = 0F (hexadecimal) = 15 (decimal)
• Crystal frequency = 11.0592 MHz

The timer counts up from the value (TH, TL) = (20, 0F) = 200F (hexadecimal) = 8207 (decimal)

So, the number of counts is (FFFF - initial count + 1) = (65535 - 8207 + 1) = 57329 counts

Each machine cycle in the 8051 is 12 oscillator periods, so with an 11.0592 MHz crystal, the time for one machine cycle is (12 / 11.0592 MHz) = 1.085069444 microseconds

The timer increments once per machine cycle, so the total time delay is (number of counts * time per count) = (57329 * 1.085069444 microseconds) = 62.201 milliseconds

So, the answer is B) 62.201 milliseconds.
