(M68000 Family)
Operation: Source ⊕ CCR → CCR
Assembler
Syntax: EORI # < data > ,CCR
Attributes: Size = (Byte)
Description: Performs an exclusive-OR operation on the condition code register using the
immediate operand and stores the result in the condition code register (low-order byte
of the status register). All implemented bits of the condition code register are affected.
Condition Codes:
X — Changed if bit 4 of immediate operand is one; unchanged otherwise.
N — Changed if bit 3 of immediate operand is one; unchanged otherwise.
Z — Changed if bit 2 of immediate operand is one; unchanged otherwise.
V — Changed if bit 1 of immediate operand is one; unchanged otherwise.
C — Changed if bit 0 of immediate operand is one; unchanged otherwise.
