Abstract
A device including a first integrated circuit (IC), a second IC configured to provide instructions to the first IC based on received data, wherein the first IC is a high-voltage IC and the second IC is a low-voltage IC, and a communication interface between the first and second ICs including a data bus of parallel data lines. The second IC is configured to select, based on the received data, one of a plurality of different communication modes for providing the instructions to the first IC via the communication interface, wherein each mode is defined by a quantity of address data and a quantity of configuration data used to provide the instructions to the first IC.
