12.3.4 Bit Manipulation Instructions

Bit operations

Mnemonic	Description of operation
BTST imm, Dn	AND the zero-extended imm8, zero-extended imm16, or imm32 with the contents
	of Dn and set the flags according to the result.
BTST imm8, (d8,An)	AND the zero-extended imm8 with the zero-extended 8-bit contents of the memory
	location specified by d8 and An and set the flags according to the result.
BTST imm8, (abs32)	AND the zero-extended imm8 with the zero-extended 8-bit contents of the memory
	location specified by abs32 and set the flags according to the result.
	This instruction proceeds through the following three stages:
	1.Transfer, with zero-extension, the 8-bit contents of the memory location specified
BSET Dm, (An)	with An to a 32-bit internal temporary register.
	2.AND the temporary register with the contents of Dm and set the flags according
	to the result.
	3.OR the temporary register with the contents of Dm and store the lowest 8 bits of
	the result in the memory location specified with An.
	This instruction proceeds through the following three stages:
	1.Transfer, with zero-extension, the 8-bit contents of the memory location specified
BSET imm8, (d8,An)	with d8 and An to a 32-bit internal temporary register.
	2.AND the temporary register with zero-extended imm8 and set the flags according
	to the result
	3.OR the temporary register with zero-extended imm8 and store the lowest 8 bits of
	the result in the memory location specified with d8 and An.
	This instruction proceeds through the following three stages:
	1.Transfer, with zero-extension, the 8-bit contents of the memory location specified
BSET imm8, (abs32)	with abs32 to a 32-bit internal temporary register
	2.AND the temporary register with zero-extended imm8 and set the flags according
	to the result.
	3.OR the temporary register with zero-extended imm8 and store the lowest 8 bits of
	the result in the memory location specified with abs32.
	This instruction proceeds through the following three stages:
	1.Transfer, with zero-extension, the 8-bit contents of the memory location specified
BCLR Dm,(An)	with An to a 32-bit internal temporary register.
	2.AND the temporary register with the contents of Dm and set the flags according
	to the result.
	3.AND the temporary register with the ones complement of the contents of Dm and
	store the lowest 8 bits of the result in the memory location specified with An.
	This instruction proceeds through the following three stages:
	1.Transfer, with zero-extension, the 8-bit contents of the memory location specified
	with d8 and An to a 32-bit internal temporary register.
BCLR imm8,(d8,An)	2.AND the temporary register with zero-extended imm8 and set the flags according
	to the result.
	3.AND the temporary register with the ones complement of zero-extended imm8
	and store the lowest 8 bits of the result in the memory location specified with d8
	and An.
