## Abstract

A method for initializing or configuring an electrical circuit, is described. The method includes reading data units stored in a memory device, using data contained in a first data unit part of the data units as a specification for use of data contained in a second data unit part of the data units, and carrying out the initialization or the configuration of the electrical circuit in a manner dependent on a content of an initialization control register contained in the electrical circuit. And in that during the initialization of the electrical circuit, the data read from the memory device can be written once or more often to the initialization control register.

## Claims

### Claim 1

A method for initializing or configuring an electrical circuit, which comprises the steps of:
reading data units stored in a memory device;
using data contained in a first data unit part of the data units as one of:
(a) an address of a register or a memory to which data contained in a second data unit part of the data units are to be written; and
(b) an indication of how the data contained in a second data unit part of the data units are to be processed; and
carrying out the initialization or the configuration of the electrical circuit in a manner dependent on a content of an initialization control register contained in the electrical circuit, and in that during the initialization of the electrical circuit, the data read from the memory device can be written once or more often to the initialization control register.

### Claim 2 (depends on 1)

The method according to claim 1, which comprises writing the data contained in the second data unit part to a storage device, selected from the group consisting of a memory and a register, contained in the electrical circuit.

### Claim 3 (depends on 2)

The method according claim 2, which comprises defining the storage device to which the data contained in the second data unit part are to be written by taking account of the data contained in the first data unit part.

### Claim 4 (depends on 3)

The method according to claim 3, which comprises using the data contained in the first data unit part as an address designating the. storage device to be written to.

### Claim 5 (depends on 1)

The method according to claim 1, which comprises setting up each of the data units with a variable length, so that the data units that are read out successively may have different lengths.

### Claim 6 (depends on 5)

The method according to claim 5, which comprises varying a length of the second data unit part in a manner dependent on the storage device which is to be written to.

### Claim 7 (depends on 5)

The method according to claim 5, which comprises providing each of the data units used with information about a length of a respective data unit.

### Claim 8 (depends on 1)

The method according to claim 1, which comprises providing each of the data units used with a third data unit part containing test data that can be used to at least one of detect and correct transmission errors.

### Claim 9 (depends on 8)

The method according to claim 8, which comprises providing each of the data units used with information about whether or not a respective data unit has a data unit part containing the test data.
