Or rather it can find code at this point. Can it create a new program does anyone know?
can you write assembly code for mc68hc05?
Yes, I can provide an example of assembly code for the MC68HC05 microcontroller. Here's a simple program that toggles an output pin on and off:
vbnet
Copy code
ORG $8000 ; start address
RESET:
LDA #%00000001 ; load binary value 00000001 into accumulator A
STA DDRB ; set data direction register B to output
CLR PORTB ; clear port B to turn off output
LOOP:
LDA PORTB ; load current value of port B into accumulator A
EOR #1 ; XOR with binary value 00000001 to toggle the LSB
STA PORTB ; store the result back to port B
BRA LOOP ; branch back to LOOP label to repeat the process
END ; end of program
This program first sets up the data direction register (DDRB) for port B as an output and clears the output by writing 0 to the port. It then enters an infinite loop where it toggles the least significant bit (LSB) of the port B output by XORing it with binary value 00000001 and writing the result back to the port. This causes the output pin to toggle on and off.
Note that this is just a simple example and you would need to modify the code to suit your specific application.
