Syntax
Operation
Data Types
Description
Performs a bitwise logical EXCLUSIVE OR of the source operand specified by op2 and the destination
operand specified by op1. The result is then stored in op1.
Flags
E
*
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. Cleared otherwise.
V Always cleared.
C Always cleared.
