(EN) LOGIC CIRCUITRY
(FR) CIRCUITS LOGIQUES
Abstract
(EN)
In an example, a logic circuitry package has a first address and comprises a first logic circuit. In some examples, the first address is an I2C address for the first logic circuit, and the package is configured such that, in response to a first command indicative of a task and a first time period sent to the first address, the first logic circuit is to, for a duration of the time period, perform a task, and disregard I2C traffic sent to the first address.
(FR)
Dans un exemple, un ensemble de circuits logiques possède une première adresse et comprend un premier circuit logique. Dans certains exemples, la première adresse est une adresse I2C Pour le premier circuit logique, et l’ensemble est configuré de façon à ce que, en réponse à une première instruction indiquant une tâche et une première période envoyée à la première adresse, le premier circuit logique soit destiné, pendant une durée de la période, à effectuer une tâche et ignorer le trafic I2C envoyé à la première adresse.
