US Patent 11364724 Logic circuitry package

A logic circuitry package for a replaceable print apparatus component includes an interface to communicate with a print apparatus logic circuit and at least one logic circuit including a memory storing a reference parameter. The at least one logic circuit is configured to receive, via the interface, a first request sent to a first address to read the reference parameter; and transmit, via the interface, the reference parameter in response to the first request. The at least one logic circuit is configured to receive, via the interface, a second request sent to a second address to implement a task; and implement the task to output a digital value via the interface in response to the second request. The reference parameter corresponds to the digital value.
