IFF the content of the interrupt enable flip-flop (IFF) is copied into the P/V flag (0 = interrupts disabled, 1 = interrupts enabled) | ||
| Flag Notation: | • = flag not affected, 0 = flag reset, 1 = flag set, X = flag is unknown, | |
| ↕ = flag is affected according to the result of the operation. | ||
| 16-byte values: | Where a 16-bit 'nn' value or address is specified: | |
|
||
| the first byte of the pair is the least significant byte. |
