MPU-1
INTRODUCTION
The Motorola M6800 Microcomputer System of standard LSI (Large Scale Integration) devices permits the systems designer to configure and connect a total system with a minimum amount of time and effort. The MC6800 Microprocessing Unit (MPU) forms the nucleus of the system. LSI modules available which may be used to configure a total system in conjunction with the MC6800 MPU, include: 1) MC6810 Random Access Memory (RAM); 2) MC6830 Read Only Memory (ROM); 3) MC6820 Peripheral Interface Adapter (PIA), and 4) MC6850 Asynchronous Communications Interface Adapter (ACIA).
The MPU communicates with the rest of the system via a 16 bit address bus and an 8 bit data bus. The 16 bit address bus provides the MPU the capability of addressing up to 64K. The 8 bit data bus is
Other features of the M6800 system include a single +5 volt supply, operation at clock rates from 100 kilohertz to 1 megahertz, plus hardware and software interrupt capability.
