INT 01 - CPU-generated - SINGLE STEP
Desc: generated after each instruction if TF (trap flag) is set; TF is
cleared on invoking the single-step interrupt handler
Notes: interrupts are prioritized such that external interrupts are invoked
after the INT 01 pushes CS:IP/FLAGS and clears TF, but before the
first instruction of the handler executes
used by debuggers for single-instruction execution tracing, such as
MSDOS DEBUG's T command
