Abstract
A method and system for operating an input/output circuit for driving peripheral devices controlled by an embedded system. For increasing the overall system availability the invention proposes to add some limited, repeatedly-performed status storing functionality preferably into a register storage of the I/O devices. The stored information can be easily exploited (i.e., read out from external of the input/output devices) via the controller of the embedded system.
