MSP432E401Y: XOR operation is not happening

Part Number: MSP432E401Y

Tool/software:

Dear TI team,

Char Cs=0x00;

Char Value;

Cs = Cs ^ Value;

While executing the above statement multiple times, the Cs value coming is 0x00 always, I mean XOR operation is not happening between Cs and Value.

What could be the reason for that.

Thanks

Kalyan

What is the value of "Value"? If Value==0, then Cs would always be ==0.

Maybe some more context would be useful.

The value of "Value" is anything except 0.

Here "Value" is a variable which varies based on the incoming data from UART.

How do you tell that this is (not) happening? [Debugger? Printf? LED? Logic analyzer?]

I'm checking the CS value in serial terminal. After XOR operation I'm sending the CS value through one of the uart.

Can you post the actual code you're using? It's hard to guess what is going wrong otherwise.
