<p>An electronic demand register (46) for an electric meter (10) includes a volatile storage (72) for normal processing of data and a non-volatile storage (64) into which data is serially written upon the occurrence of conditions which may threaten the integrety of such data and from which the data is again retrieved when the condition no longer exists. The data formats for transmission of the data to the non-volatile memory (64) and for receiving it therefrom do not agree with the data formats which the volatile storage (72) must have. A communications buffer (76) assembles a data (64) package for transmission to the non-volatile memory (64) which has a format which can be suitably serially transmitted to the non-volatile memory (64) and be properly interpreted there due to the manner in which the non-volatile memory (64) recognizes and stores data. In addition, the communications buffer (76) receives the serial data from the non-volatile memory (64) and, by left shift and selection of only valid portions of the data, assembles data suitable for transmission to the volatile memory (72).</p> |
