Abstract
An electronic fault detection unit is provided that has a first register, a second register, a comparator circuit, and a timer circuit. The first and second register can be written from a first software portion, and a second software portion, respectively. The comparator circuit is arranged to detect that both the first and second register have been written, verify a relationship between first data written to the first register and second data written to the second register, and signal a fault upon said verification failing. The timer circuit is arranged to signal a fault if said verification of the comparator circuit does not occur within a time limit.
