BIC Instruction

Purpose:

To perform complemented AND of two integers

Format:

opcode mask.rx, dst.mx
opcode mask.rx, src.rx, dst.wx

Operation:

dst <- dst AND NOT(mask);
dst <- src AND NOT(mask);

Condition
Codes:

N <- dst LSS 0;
Z <- dst EQL 0;
V <- 0;
C <- C;

Exceptions:

None

Opcodes:

8A	BICB2	Bit Clear Byte 2 Operand
8B	BICB3	Bit Clear Byte 3 Operand
AA	BICW2	Bit Clear Word 2 Operand
AB	BICW3	Bit Clear Word 3 Operand
CA	BICL2	Bit Clear Long 2 Operand
CB	BICL3	Bit Clear Long 3 Operand

Description:

In the 2 operand format, the mask operand is ANDed with the ones complement of the destination operand and the destination operand is replaced by the result.

In the 3 operand format, the mask is ANDed with the ones complement of the source operand and the destination operand is replaced by the result.
