Hello,

I would do something like this.

Code: Select all

Counter = 0b01101101

A is equal to counter bit shifted right by four places and then masked with 0b00001111

Code: Select all

A = (Counter >> 4) & 0x0F

B is equal to counter masked with 0b00001111

Code: Select all

B = Counter & 0x0F

Thanks, but this is the only way?
Counter value is not already known، What about addressing?

There are many ways to crack a nut, I think I'm missing the bigger picture of what you're actually trying to do.

If it's split a byte up into two nibbles then my code is probably as efficient as you can get.

Counter value is not already known

I simply provided the counter = line of code as example of how to initialise the counter variable in binary if you need to.

What about addressing?

Again I'm not really sure what you mean by this.
