5.3.3.6 BIT MANIPULATION INSTRUCTIONS. 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.
