Two Bit request (sic)

[SteveB]

Lots of ways to do this, here’s one:

If the pins are two adjacent pins of a port (for example portA.2 and porta.3) then you could use a bit mask and then shift the bit to the right as needed. So, using A.2 and A.3 it would be:

MODEval= PortA & %00001100
MODEval = MODEval >> 2

This will give you a value of MODE from 0-3.

Also, you would even skip the shift and just use the CASE to check for values of 4, 8, and 12.

And, if the pins are not consecutive, you can still use a bit mask and then check the values:

MODEval = PortA & %10001000
SELECT CASE MODEval
	CASE 8
    		Statement... 
	CASE 128 
    		Statement...
	CASE 136 
    		Statement...
	{CASE ELSE 
    		Statement...}
END SELECT

HTH,
