Thirteen Addressing Modes. True Indexing Capability. • Programmable Stack Pointer. • Variable Length Stack. • Interrupt Capability. • Non-maskable Interrupt.
Thus the 6800 and 6502 stack pointers always point to one address below the current stack limit whereas the 6809 stack pointer always points to the last
Zero Extension in LSR Addressing Modes Problem: Tiny HW Stack Slow SW Stack. The 6502's 256-byte hardware stack pointer is too small for C!
The 6502 has a 64K address space requiring 16 bits per absolute address
