A control module ( 1 ) having the following elements: a read-only memory (ROM 2 ), a temporary buffer ( 6 ), into which the data of said ROM ( 2 ) can be transferred in order to be accessible from outside the control module, a read controller ( 3 ), for selecting at each cycle the portions of said ROM transferred into said temporary buffer, wherein the portions selected by said read controller ( 3 ) depend on the contents of said ROM. One advantage of the invention is the reduction of the electric consumption, since the ROM does not have to be read when the data are already available in the temporary buffer. |
