- 6809 — Motorola 6809
- motorola 6809 — (processor) (MC6809) An eight-bit microprocessor from Motorola, Inc.. The 6809 was a major advance over both its predecessor, the Motorola 6800 and the 6502. The 6809 had two 8-bit accumulators, rather than one in the 6502, and could combine them into a single 16-bit register. It also featured two index registers and two stack pointers, which allowed for some very advanced addressing modes. The 6809 was source compatible with the 6800, even though the 6800 had 78 instructions and the 6809 only had around 59 (including a SEX instruction). Some instructions were replaced by more general ones which the assembler would translate and some were replaced by addressing modes. The 6809 had one of the first multiplication instructions of the time, 16-bit arithmetic and a special fast interrupt. But it was also highly optimised, gaining up to five times the speed of the 6800 series CPU. Like the 6800, it included the undocumented HCF (Halt and Catch Fire) bus test instruction. The Hitachi 6309 was a version with extra registers. The 6809 was used in the UK "Dragon 32" personal computer and was followed by the Motorola 68000. Lennart Benschop <[email protected]> posted a emulator (originally called "usim") and a cross-assembler to Usenet newsgroup alt.sources on 1993-11-03. Ray P. Bellis <[email protected]> released a version 0.11.
