An integrated-circuit device comprises a source register in a reset domain, a destination circuit outside the reset domain, and a reset checking circuit. The checking circuit comprises a buffer outside the reset domain for receiving data values output by the source register, a reset detector, and reset checking logic. The checking logic detects a new data value output by the source register, checks whether a reset of the reset domain has been detected, and contingently outputs a control signal for controlling whether the destination circuit receives the new data value from the buffer. The reset detector signals whether a reset has been detected by using a feedback path to hold a predetermined value in a resettable latch until the latch receives a reset signal, and to hold a different value in the latch after receiving a reset signal.

Circuitry for transferring data across reset domains

A microcontroller device comprises at least one processor (), one or more peripheral systems () and a resource supply module (). The processor () and peripheral system(s) () are each arranged to generate a signal when they require power and/or a clock signal. These signals stimulate the resource supply module () to supply the requested resource.
