Final answer:
The question requires writing an assembly program for Keil software to count to 100 using Timer 1, then generate a 5KHz square wave on P1.2, showing the count on Port 0. A generic code template is provided as an example but needs detailed adjustments for practical implementation.
Step-by-step explanation:
The question involves writing a program in Assembly language for the Keil software platform. Specifically, it asks for a program to utilize Counter 0, count to 100 using Timer 1, and upon reaching that count, generate a 5KHz square waveform on pin P1.2. Additionally, the count value in Timer 1 (presumably TL1) should be displayed on Port 0.
To achieve this, one would have to initialize Timer 1 in mode 1 or mode 2, depending on the exact microcontroller being used (as different models can have different configurations). The primary task would be setting up the timer, handling the overflow interrupt to toggle P1.2, and displaying the count on Port 0.
Below is a simplified example code template that could serve as a starting point:
ORG 0000h
START: ; Initialization code
MOV TMOD, #01h ; Timer 1 in mode 1
MOV TL1, #Initial Value ; Load TL1 with the initial count
MOV TH1, #Initial Value ; Load TH1 if necessary
SETB TR1 ; Start Timer 1
HERE: JNB TF1, HERE ; Wait for overflow
CLR TF1 ; Clear the overflow flag
CPL P1.2 ; Toggle P1.2 to create waveform
INC TL1 ; Increment the count
MOV A, TL1 ; Move count to accumulator
MOV P0, A ; Display count on Port 0
SJMP HERE ; Jump back to loop
END
Please note that the code provided above is very generic and will need to be adjusted to match the specific requirements of the 5KHz waveform generation, taking into account the microcontroller's clock frequency and the method chosen to reach the desired count. Moreover, additional code might be necessary to handle initialization specifics and to loop the counting process correctly.
