Freerunning the M68000.
Electronics Test, pp.124, April 1984.
Freerunning represents the first step in troubleshooting a microprocessorbased board using signature analysis (SA). Freerunning essentially involves breaking all feedback paths from the board's circuits to the microprocessor and forcing the microprocessor to permanently execute a single-byte instruction that causes continuous cycling through the entire address field. In this short paper, freerunning of M68000 microprocessor is described.
