Title
(EN) LOGIC CIRCUITRY
(FR) CIRCUITERIE LOGIQUE
Abstract
(EN)
In an example, a logic circuitry package is configured to communicate with a print apparatus logic circuit. The logic circuitry package may be configured to respond to communications sent to a first address and to at least one second address. The logic circuitry package may comprise a first logic circuit, wherein the first address is an address for the first logic circuit. The package may be configured such that, in response to a first command indicative of a task and a first time period sent to the first address, the package is accessible via at least one second address for a duration of the time period.

L'invention concerne, selon un exemple, un boîtier de circuiterie logique conçu pour communiquer avec un circuit logique d'appareil d'impression. Le boîtier de circuiterie logique peut être conçu pour répondre à des communications envoyées à une première adresse et à au moins une seconde adresse. Le boîtier de circuiterie logique peut comprendre un premier circuit logique, la première adresse étant une adresse pour le premier circuit logique. Le boîtier peut être conçu de telle sorte que, en réponse à une première commande indicative d'une tâche et à une première période temporelle envoyée à la première adresse, le boîtier est accessible par l'intermédiaire d'au moins une seconde adresse pendant une durée de la période temporelle.
