A parameterized register interface of an integrated circuit and methods of register programming. An integrated circuit includes a digital controller, at least one client comprising at least one programmable register and a parameterized bus coupled to the digital controller and the client. The digital controller is configured to: transfer, via the parameterized bus, address data and/or register data between the digital controller and the client according to one or more interface signals conveyed over the parameterized bus; generate a transaction command comprising at least one transaction specific to the programmable register of the client, the transaction command generated according to a predetermined register programming protocol; and transfer, via the parameterized bus, the transaction command together with at least one predetermined combination of the interface signals to the client. The programmable register is configured to perform the transaction in accordance with the transaction command.

Parameterized register programming protocol (RPP) to save layout routing area

A mixed signal system includes a digital domain and an analog domain. The analog domain includes a plurality of BARs. Each BAR includes addressable registers. The digital domain includes an interface configured to communicate with the analog domain, e.g., write data to an addressable register within a BAR by transmitting a first select signal to select a first BAR of the plurality of BARs. The interface transmits an address of the addressable register of the first BAR and broadcasts the write data to the first BAR and at least one BAR other than the first BAR. The analog domain transmits data from a second BAR of the plurality of BARs to the digital domain by gating a select BAR signal associated with each BAR with its corresponding content stored therein to form respective BAR output and further by gating the respective BAR outputs with one another.
