WebDec 15, 2013 · For example, the bitwise AND of 10110111 and00001101 is 00000101. In a nutshell, “& 0xff” effectively masks the variable so it leaves only the value in the last 8 bits, and ignores all the rest of the bits. It’s seen most in cases like when trying to transform color values from a special format to standard RGB values (which is 8 bits long). WebMay 17, 2024 · Right alignment would make the LSB from the A/D bit 0. Left alignment indicates the same but the MSB of the A/D result would be the MSB of the register. The bits will not be seperated and the unused register values will filled with (read data sheet). Think 12 bit result from A/D 16 bit register. \$\endgroup\$ –
