Address of next instruction in main program to be
executed upon return from subroutine
Most significant byte of return address
Least significant byte of return address
Shaded cells show stack pointer position after
operation is complete.
8-bit direct address ($0000–$00FF) (high byte
assumed to be $00).
8-bit positive offset $00 (0) to $FF (256) is added
to index.
High-order byte of 16-bit extended address.
Low-order byte of 16-bit extended address.
Signed-relative offset $80 (–128) to $7F (+127)
(offset relative to the address following the
machine code offset byte).
