appropriately. When a data register is the destination, any of the 32 bits can be
specified by a modulo 32- bit number. When a memory location is the destination, the
operation is a byte operation, and the bit number is modulo 8. In all cases, bit zero
refers to the least significant bit. The bit number for this operation can be specified in
either of two ways:
X — Not affected.
N — Not affected.
Z — Set if the bit tested is zero; cleared otherwise.
V — Not affected.
C — Not affected.
1. Immediate—The bit number is specified in a second word of the instruction.
2. Register—The specified data register contains the bit number.
