microcontroller memory. Each reexecution subroutine corresponds to a frag-
ment of the program that can be identified by the starting addresses of these
subprograms in memory. If an error is detected at a certain checkpoint, the
microcontroller intercepts the program for the bioassay and points the pro-
gram counter to the starting address of the corresponding subprogram. In this
way, control-flow feedback is implemented based on an interrupt-handling
mechanism implemented in the software.
