A microprocessor comprises a timer capable of resetting the device and a plurality of hardware registers () arranged logically so that a collective predetermined state of the registers () prevents the device from resetting. The device further comprises software () with a plurality of functions arranged to place said registers () in said predetermined state if each of said functions has executed properly.

Peripherals () are connected to a processor () and a programmable peripheral interconnect () is connected to each peripheral. One of the peripherals () is configured to signal an event to the interconnect, and one of the peripherals () is configured to respond to a task signal from the interconnect by performing a task. The task-receiving peripheral () has a task register (), addressable by the processor (), and performs the task in response to a change in the contents of the register (). The interconnect () accesses a memory () in which a mapping is stored between an event of a first peripheral () and a task of a second peripheral (), the mapping comprising (i) an identification of the event, and (ii) the address of a task register (). The mapping causes the interconnect () to provide a channel by sending a task signal to the second peripheral () in response to a signal of the event from the first peripheral ().
