Abstract: A logic circuitry package for a replaceable print apparatus component includes an interface to communicate with a print apparatus logic circuit, and a logic circuit having a communication address to communicate with the print apparatus logic circuit. The logic circuit is configured to detect, via the interface, communications that include an other communication address. The logic circuit is configured to respond, via the interface, to a command series directed to the logic circuit that include the communication address of the logic circuit, based on the detected communications.

Abstract: A logic circuit for a replaceable print component is configured to, in response to a plurality 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 sub-class parameters, and at least one read request, generate count values in a count value range defined by a highest and lowest count value.

Abstract: A logic circuitry package for a replaceable print apparatus component comprises an interface to communicate with a print apparatus logic circuit, and at least one logic circuit. The logic circuit may be configured to identify, from a command stream received from the print apparatus, parameters including a class parameter, and/or identify, from the command stream, a read request, and output, via the interface, a count value in response to a read request, the count value based on identified received parameters.

Abstract: In an example, a logic circuit comprising a communications interface including a data contact to communicate via a communications bus, an enablement contact, separate from the communication interface, to receive an input to enable the logic circuit, and at least one memory register, comprising at least one reconfigurable address register. The logic circuit may be configured, such that, when enabled, it responds to communications sent via the communication bus which are addressed to the address held in a reconfigurable address register.

Abstract: In an example, a method comprises, by logic circuitry associated with a replaceable print apparatus component installed in a print apparatus, receiving a sensor data request and determining whether the request is for data indicative of a print material level or for data indicative of a pressurisation event. In the event that the request is a request for data indicative of the print material level, the method may comprise responding with a first data response in a first value range; and in the event that the request is a request for data indicative of a pressurisation event, the method may comprise responding with a second data response in a second value range.
