**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).
dd
= 8-Bit Direct Address ($0000 –$00FF) (High Byte Assumed to be $00)
ff
= 8-Bit Positive Offset $00 (0) to $FF (255) (Is Added to Index)
hh
= High Order Byte of 16-Bit Extended Address
ii
= One Byte of Immediate Data
jj
= High Order Byte of 16-Bit Immediate Data
kk
= Low Order Byte of 16-Bit Immediate Data
ll
= Low Order Byte of 16-Bit Extended Address
mm
= 8-Bit Bit Mask (Set Bits to be Affected)
rr
= Signed Relative Offset $80 (– 128) to $7F (+ 127)
(Offset Relative to the Address Following the Machine Code Offset Byte)
