Register (AM 1)

Syntax

op2

where:

op2	Specifies a register containing the value of the instruction operand.

Description

The data-processing operand "register" performs the following operation (pseudo-code description):

addr_mode = op2
shifter_carry_out = C flag

The data-processing operand op2 directly provides the value of a register. The carry out from the shifter is the C flag.

Encoding

31			28	27	26	25	24			21	20	19			16
condition				0	0	0	opcode				S	op1

15			12	11	10	9	8	7	6	5	4	3			0
dest				0	0	0	0	0	0	0	0	op2

Note

This instruction is encoded as a logical shift left by immediate with a shift of zero ( sh_imm == 0 ).
If R15 is specified as register op2 or op1 , the value used is the address of the current instruction plus 8.

Example

ADC    R1, R12, R7
