The purpose of this lab is to control and program the MC8051 Counters of the micro-controller in a given sequence. The program displays current count of Counter 0 on port 1 (P1) and Counter 1 on port 2 (P2). The initial THO value is FOH and TH1 is E1H. Counter0 and Counter1 are programmed in mode 2 using the polling mode, no interrupts. The status of TFO and TF1 are displayed on Port 3 bit 0 (P3.0) and bit 1 (P3.1) respectively. Steps 1. First, configure and initialize the required parallel ports; P1, P2, and P3. The Main program starts at code memory address 40H. The main program only function is updating P1 & P2 and displaying the two overflow flags on port 3. 2. Second, in the main program configure the two Counters for Mode 2 with the given initial two counts. Start Counterro & Counter1, initiate the external clock pulses on your Keil simulator, and display its accumulated count values on P1 & P2. Continue updating the status of TFO & TF1 on P3.0 & P3.1. 3. Third, configure the debugger display to include the Timer0, Timer1, P1, P2, P3, and the Clock Control windows. Make sure that the Timers windows are configured for no external interrupts and external pin clocks. The clock window can be used to control the CPU clock speed, which can help during the debugging process. 4. Run the program and monitor all displayed windows. Verify the operation of the two Counters, TFO & TF1, and the three display ports. 5. Test and debug your program. Also, document and submit your final report along with the well documented list file. You can slow the Counters and Ports update by controlling the MC clock using the clock window in the PREPHERALS selection.

Hello, can you please help me do this exercise. Using Keil uVision 5. Thanks
Transcribed Image Text:The purpose of this lab is to control and program the MC8051 Counters of
the micro-controller in a given sequence. The program displays current
count of Counter 0 on port 1 (P1) and Counter 1 on port 2 (P2). The initial
THO value is FOH and TH1 is E1H. Counter0 and Counter1 are
programmed in mode 2 using the polling mode, no interrupts. The status of
TFO and TF1 are displayed on Port 3 bit 0 (P3.0) and bit 1 (P3.1)
respectively.
Steps
1. First, configure and initialize the required parallel ports; P1, P2, and
P3. The Main program starts at code memory address 40H. The main
program only function is updating P1 & P2 and displaying the two
overflow flags on port 3.
2. Second, in the main program configure the two Counters for Mode 2
with the given initial two counts. Start Counterro & Counter1, initiate
the external clock pulses on your Keil simulator, and display its
accumulated count values on P1 & P2. Continue updating the status
of TFO & TF1 on P3.0 & P3.1.
3. Third, configure the debugger display to include the Timer0, Timer1,
P1, P2, P3, and the Clock Control windows. Make sure that the
Timers windows are configured for no external interrupts and external
pin clocks. The clock window can be used to control the CPU clock
speed, which can help during the debugging process.
4. Run the program and monitor all displayed windows. Verify the
operation of the two Counters, TFO & TF1, and the three display
ports.
5. Test and debug your program. Also, document and submit your final
report along with the well documented list file. You can slow the
Counters and Ports update by controlling the MC clock using the
clock window in the PREPHERALS selection.
