Title
(EN) LOGIC CIRCUITRY PACKAGE
(FR) BOÎTIER DE CIRCUITERIE LOGIQUE
Abstract
(EN)
A logic circuitry package for a replaceable print apparatus component includes an interface to communicate with a print apparatus logic circuit and at least one logic circuit. The at least one logic circuit is configured to receive, via the interface, a request to replace an internal clock signal from an internal clock generator of the logic circuitry package with an external test clock signal. The at least one logic circuit is configured to receive, via the interface, the external test clock signal. The at least one logic circuit is configured to replace the internal clock signal with the external test clock signal in the logic circuitry package.

Selon l'invention, un boîtier de circuiterie logique pour un composant d'appareil d'impression remplaçable comprend une interface pour communiquer avec un circuit logique d'appareil d'impression et au moins un circuit logique. Le ou les circuits logiques sont configurés pour recevoir, par l'intermédiaire de l'interface, une demande de remplacement d'un signal d'horloge interne provenant d'un générateur d'horloge interne du boîtier de circuiterie logique par un signal d'horloge de test externe. Le ou les circuits logiques sont configurés pour recevoir, par l'intermédiaire de l'interface, le signal d'horloge de test externe. Le ou les circuits logiques sont configurés pour remplacer le signal d'horloge interne par le signal d'horloge de test externe dans le boîtier de circuiterie logique.
