Bit manipulation operations are accomplished using the following instructions: bit test (BTST), bit test and set (BSET), bit test and clear (BCLR), and bit test and change (BCHG). All bit manipulation operations can be performed on either registers or memory. The bit number is specified as immediate data or in a data register. Register operands are 32 bits long, and memory operands are 8 bits long. Table 5-8 is a summary of bit manipulation instructions. Table 5-8.
