  • Patent number: 6223241
    Abstract: The microcontroller accesses a battery of hidden registers used essentially in the field of emulation. The fact that there is a large number of hidden registers means that it is not possible to assign them an address by which they can be accessed directly. Since this battery of hidden registers has to be accessible by a host circuit and by a microprocessor, recourse is had to a method of indirect addressing by means of two peripheral control registers. A priority signal obliges the microprocessor to wait for the read and write resources to be released by the host circuit to perform these instructions.

  • Patent number: 6182207
    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.
