MULTIPLY

Mnemonic	Description of operation
MUL Dm, Dn	Multiplies the 32-bit signed integer multiplicand in Dm by the 32-bit signed
	integer multiplier in Dn and store the upper 32 bits of the product in MDR and
	the lower 32 bits in Dn.
MULU Dm, Dn	Multiplies the 32-bit unsigned integer multiplicand in Dm by the 32-bit
	unsigned integer multiplier in Dn and store the upper 32 bits of the product in
	MDR and the lower 32 bits in Dn.

DIVIDE

Mnemonic	Description of operation
DIV Dm, Dn	Divide the 64-bit signed integer dividend with its upper 32 bits in MDR and
	its lower 32 bits in Dn by the 32-bit signed divisor in Dm and store the 32-bit
	remainder in MDR and the 32-bit quotient in Dn.
DIVU Dm, Dn	Divide the 64-bit unsigned integer dividend with its upper 32 bits in MDR
	and its lower 32 bits in Dn by the 32-bit unsigned divisor in Dm and store the
	32-bit remainder in MDR and the 32-bit quotient in Dn.

INC

Mnemonic	Description of operation
INC Dn	Add 1 to the contents of Dn and store the result in Dn.
INC An	Add 1 to the contents of An and store the result in An.
INC4 An	Add 4 to the contents of An and store the result in An.

COMPARE source with destination

Mnemonic	Description of operation
CMP Dm, Dn	Subtract the contents of Dm from Dn and set the flags according to the result.
CMP Dm, An	Subtract the contents of Dm from An and set the flags according to the result.
CMP Am, Dn	Subtract the contents of Am from Dn and set the flags according to the result.
CMP Am, An	Subtract the contents of Am from Dn and set the flags according to the result.
CMP imm, Dn	Subtract the sign-extended imm8, sign-extended imm16, or imm32 from Dn
	and set the flags according to the result.
CMP imm, An	Subtract the zero-extended imm8, zero-extended imm16, or imm32 from An
	and set the flags according to the result.
