Infinity or until reset occurs
12 cycles are used beginning with the opcode fetch. A wait state is entered which remains in effect for an integer number of MPU E-clock
cycles (n) until an interrupt is recognized. Finally, two additional cycles are used to fetch the appropriate interrupt vector (14 + n total).
= 8-bit direct address ($0000–$00FF) (high byte assumed to be $00)
= 8-bit positive offset $00 (0) to $FF (255) (is added to index)
= High-order byte of 16-bit extended address
= One byte of immediate data
= High-order byte of 16-bit immediate data
= Low-order byte of 16-bit immediate data
= Low-order byte of 16-bit extended address
= 8-bit mask (set bits to be affected)
= Signed relative offset $80 (–128) to $7F (+127)
