breakpoint — A number written into the break address registers of the break module. When a
break interrupt — A software interrupt caused by the appearance on the internal address bus
bus — A set of wires that transfers logic signals.
bus clocks — There are two bus clocks, IT12 and IT23. These clocks are generated by the CGM
byte — A set of eight bits.
C — The carry/borrow bit in the condition code register. The CPU08 sets the carry/borrow bit
