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.
