requests from peripheral devices for processor action; the bus error and reset inputs are
used for access control and processor restart. The internal exceptions are generated by
instructions, address errors, or tracing. The trap (TRAP), trap on overflow (TRAPV), check

addresses, and privilege violations cause exceptions. Tracing is similar to a very high
priority, internally generated interrupt following each instruction.
