Abstract
(EN)
A logic circuit for a replaceable print component is configured to, in response to a series of commands including a first command specifying the new I2C communications address and a first calibration parameter, a second command specifying the new I2C communications address and a second calibration parameter, a third command specifying the new I2C communications address and a class parameter, and/or fourth commands specifying the new I2C communications address and subclass parameters, and at least one read request, generate count values in a count value range defined by a highest and lowest count value.

L'invention concerne un circuit logique pour un composant d'impression remplaçable qui est configuré, en réponse à une série de commandes comprenant une première commande spécifiant la nouvelle adresse de communication I2C et un premier paramètre d'étalonnage, une seconde commande spécifiant la nouvelle adresse de communication I2C et un second paramètre d'étalonnage, une troisième commande spécifiant la nouvelle adresse de communication I2C et un paramètre de classe, et/ou des quatrièmes commandes spécifiant la nouvelle adresse de communication I2C et des paramètres de sous-classe, et au moins une requête de lecture, pour générer des valeurs de comptage dans une plage de valeurs de comptage définie par une valeur de comptage la plus élevée et la plus faible.
