Electrical energy meter with programmable register component

A programmable solid-state electronic register component for an electrical energy meter, comprising:

• a mode table;
• a plurality of task tables;
• a plurality of modules;
• wherein said mode table comprises an array of task pointers to respective ones of said plurality of task tables,
• wherein each of said plurality of task tables comprises an array of module pointers to corresponding ones of said plurality of modules,
• wherein each of said plurality of modules comprises a plurality of instructions to be executed during the performance of a corresponding task, which is included in at least one of predetermined groups of tasks, and
• wherein each of said predetermined groups of tasks is defined by one of said task tables and corresponds to a predetermined mode of operation such as a time-of-use and demand mode of operation or a demand-only mode of operation;
• and
• micro-controller means for operating said register component in said predetermined mode of operation by executing a corresponding predetermined group of tasks, said micro-controller means comprising
• means for indexing to a task pointer in said mode table to thereby select one of said predetermined groups of tasks, said task pointer corresponding to a selected task table,
• means for executing said one of said predetermined groups of tasks by repeatedly indexing said selected task table to respective module pointers, and
• means for executing said plurality of modules corresponding to said respective module pointers.
