Hello friends,

I am a beginner in microprocessor and system designing and I stuck in one place in my project where I need to write a program.

My question in what way would you write a sample programming instructions that tests bit 3 of an input signal coming from port 09h and outputs the word to port 09FBh if this bit is set or to port 0Ah if this bit is reset?

And yes, the instructions are to be written in assembly language.
Thanks alot in advance
