Mc6809-mc6809e
The addressing modes of any microprocessor provide it with the capability to efficiently address memory to obtain data and instructions The MC6809 and MC6809E |
How many instructions does the 6809 have?
The 6809 has a large number of addressing modes that the 6502 lacks.
The 6502 has a single addressing mode not present in the 6809.
The 6809 has hardware multiply.
The 6502 generally has less powerful instructions, but they are generally faster.What are the addressing modes of 6809?
The 6809 has a very powerful addressing mode called direct page addressing.
This way all 256 bytes of any page in memory can be addressed with only 8 bits.
These 256 addresses can be considered the "registers" of the 6809What is the difference between 6502 and 6809?
Three prioritized, vectored, hardware interrupt levels are available: non-maskable, fast, and normal.
The highest and lowest priority interrupts, non-maskable and interrupt request respectively, are the normal interrupts used in the M6800 family.
