Operation
(op1) ← (op1) + (op2) + (C)
Description
Performs a 2s complement binary addition of the source operand specified by op2, the
destination operand specified by op1 and the previously generated carry bit. The sum is
then stored in op1. This instruction can be used to perform multiple precision arithmetic.
CPU Flags
E Set if the value of op2 represents the lowest possible negative number.
Cleared otherwise. Used to signal the end of a table.
Z Set if result equals zero and previous Z flag was set. Cleared otherwise.
V Set if an arithmetic overflow occurred, i.e. the result cannot be
represented in the word data type. Cleared otherwise.
C Set if a carry is generated from the most significant bit of the word data
type. Cleared otherwise.
N Set if the most significant bit of the result is set. Cleared otherwise.
