I am using C8051F044R for my project.
There is a need to find out if the value read and stored in 3 variables is greater than 0649C6h .
Please can someone give me tips on how to go about it?

Basically I read the port 3 times and get 3 bytes, let us say,
05h,45h,44h which correspond to "054544h" and I will have to
see if the above value is greater than 0649C6h. Since C8051F044R is a 8 bit micro-controller
we can process only 8 bits at a time. But 0649C6h or 054544h is a 24 bit number.
I need some help on 24 bit number comparison in a 8 bit micro-controller. I did search the forum for sample code and did not find any.

Thanks
