Abstract
To accelerate read operations, or the operations that modify the operating parameters of a microcontroller, an interface is provided with three registers—an address register, an instruction and data register, and an auxiliary register. The instruction and data register supports the auxiliary register by indirect addressing. The address register is furthermore provided with an incrementation circuit mechanism for indirect incrementation. With the indirect addressing and the automatic incrementation, the number of external operations are reduced for continuous read or write operations.
