A method for controlling a peripheral system and a fuel cell system using the same. Consequently, the analog stages of the IC can be tested and debugged in isolation without the need for switches in the signal path through the cores. The pendant remains turned off, until activated by the user. The tubs fasten mechanically to the sides of the center sill. The system then performs a data access operation as specified by the data access request using a second data reference based upon either the history cache entry or the partition cache entry. Corresponding micromechanical components are also provided.
