279 / 346 page ![]() Obsolete Product(s) - Obsolete Product(s) ST10F296E Register set 279/346 IDMEM register IDPROG register Note: All identification registers are read-only registers. The values written inside different identification register bits are valid only after the Flash initialization phase has been completed. When code execution starts from the internal memory (pin EA held high during reset), the Flash has completed initialization and the identification register bits can be read. When code execution starts from the external memory (pin EA held low during reset), Flash initialization has not been completed and the identification register bits cannot be read. The user can poll bits 15 and 14 of the IDMEM register. When both these bits are read low, Flash initialization can be completed and all identification register bits can be read.
