Thank you so much for your reply,

The bitwise operators work at the bit level. It will do a bitwise AND on each and every bit. So, if the low-bit of Tx_Buffer is 1, the output will be 1. Otherwise it will be 0.

Assuming Tx_Buffer = 0x41, the comparison would look like:

    
  0000 0001
& 0100 0001
-----------------
  0000 0001
