).
• ON if C is a word address and bits 9, 11, and 15 of C indicate BCD input, but S is not BCD.
• ON if C is a word address and bit 9 of C indicates floating-point data, but S is a one-word constant.
• ON if C is 0000 or 0001 but S is not BCD between 0000 and 0900.
• OFF in all other cases.
Equals Flag = • ON if the result is 0.
• OFF in all other cases.
Negative Flag N • ON if bit 15 of R is ON.
• OFF in all other cases.
