Can be used only for register A, not any other register Determine if R5 contains the value 0. If so, put 55H in it. Machine cycles Time to execute a 1 1x1. Adding the two instructions outside loop we have For HERE loop, we have 4x x1. Delay P1.
SETB P1. CPL P1. JNB P2.
Climate Change and Migration
JB P1. JNB P1. If it goes high, it means that the oven is hot. Whenever it goes high, send a high-to-low pulse to port P1. Checking an HERE: Reading Single Solution: MOV C,P1. Port are two possibilities: It reads the internal latch of the port and brings that data into the CPU 2. This data is ANDed with the contents of register A 3. The result is rewritten back to the port latch 4. Y CPL P1. Y CLR P2. Reading the port 2.
Modifying it 3. Indexed Solution: BIT Solution: JB PSW. If so, send it to P2. If not, make it even and then send it to P2. Write a program to save the status of P1. CLR 06 ;clear bit addr. Write a program to get the status of the switch and send it to the LED. Monitor the bit continuously.
Using BIT Solution: Write a program to check the status of the switch and make the following decision. Also, as you place a byte in upper RAM, give a copy to P0.
Place the sum in R7 and R6; R6 should have the lower byte. To correct this problem, the programmer must add 6 to the low digit: In other word, while the source but not after INC can be an operand of any addressing mode, the destination must be in register A in order for DA to work.
The final result is in BCD format. The result must be in BCD. Add it to the minuend A Subtraction of 3. A MOV B, 10 ;load 10 to reg. Save it in R7, R6 and R5.
After each division the remainder is saves.
Write the magnitude of the number in 8-bit binary no sign 2. Invert each bit 3. If it does, send 99H to P2; otherwise, it stays cleared. XRL can be used to Solution: If both registers have the same value, 00 is placed in A. Instruction According to the test results, place the temperature value into the registers indicated by the following. Put two highs at the start and end of the data. Send the byte LSB first.
Serializing Data Solution: MOV C,P2. D7-D4 D3-D0 after: Single Bit Solution: Ports P0 — P3 are bit- Solution: This is widely used for the new generation of microcontrollers. Using the inverting and Ex-OR operators, respectively. Bit-wise Solution: Checksum Byte Solution: RAM Data Solution: Examine the contents of the code space to locate the values. The LSB should go out first. The MSB should go out first.
The LSB should come in first. The MSB should come in first. Verify also that the information is not corrupted. FILE Solution: We convert the value from hex to binary.
From Figure we have: Start the timer Program 4. Stop the timer 6. Clear the TF flag for the next round 7.
TMOD is loaded. Steps to Mode 1 6. Timer 0 counts up with the passing of each clock, which is provided by the crystal oscillator. At that point, the JNB instruction falls through.

In other words, Timer 0 counts up each 1. In the timer delay calculation of Example , we did not include the overhead due to instruction in the loop.
To get a more accurate timing, Mode 1 we need to add clock cycles due to this instructions in the loop. CLR P2. This plus Rolling over to 0 goes through a total of clock cycles, where each clock is 1. Find the delay in ms.
To get the largest delay we make TL and TH both 0. Programming CLR P2. As a result, it goes through a total Of states. In your calculation do not include the overhead due to Instructions in the loop. Also notice that the high portion and low portion of the square wave pulse are equal. In the above calculation, the overhead due to all the instruction in the loop is not included.
Divide the desired time delay by 1. Perform — n, where n is the decimal Values value we got in Step1 3. Show the program for timer 0 to create a pulse width of 5 ms on P2.
Mode 1 Solution: Programming This means that out of many 1. To get that, we divide one by the other. Mode 1 This is similar to Example , except that we must toggle the bit to generate the square wave. Look at the following steps. The program is as follow. Start timer 4. Clear the TF flag 6. First notice the target address of SJMP. In mode 2 we do not need to reload TH since it is auto-reload. Steps to Mode 2 You can use the Windows scientific calculator to verify the result Program provided by the assembler.
Remember that we only use the right two digits and ignore the rest since our data is an 8-bit data. Since ports are set up for output when the is powered up, we make P3.
In other words, we must configure set high the T1 pin pin P3. Use Timer 0, mode 1 bit to create the delay. Accessing memory using various addressing modes Extra byte on-chip RAM in Section 6.
