Title
(EN) LOGIC CIRCUITRY
(FR) CIRCUIT LOGIQUE
Abstract
(EN)
A logic circuitry package for association with a replaceable print apparatus component comprises: logic and a serial data bus interface, wherein the serial data bus interface is to interface with a serial data bus of a print apparatus, and, wherein the logic is, in response to a first command sent to the logic circuitry package via the serial data bus connected to the serial data bus interface, the first command including a time period, to generate a low voltage condition on the serial data bus for a duration based on the time period, and, after the duration, return to a default voltage condition on the serial data bus.
(FR)
L'invention concerne un boîtier de circuit logique destiné à être associé à un composant d'appareil d'impression remplaçable, comprenant : une logique et une interface de bus de données série, l'interface de bus de données série étant destinée à s'interfacer avec un bus de données série d'un appareil d'impression. La logique, en réponse à une première instruction envoyée au boîtier de circuit logique par le biais du bus de données série connecté à l'interface de bus de données série, la première instruction contenant une période, est conçue pour générer une condition de basse tension sur le bus de données série pendant une durée sur la base de la période et, après la durée, revenir à une condition de tension par défaut sur le bus de données série.
