ABSTRACT:
An electronic apparatus includes a controller having an interface part communicating with an external host apparatus and a status register group, and having a plurality of functional units communicating with the host apparatus via the interface part, respectively. The status register group includes operable status registers corresponding to the functional units respectively and indicating whether or not the corresponding functional units are in an operable state, and processing status registers corresponding to the functional units respectively and indicating whether or not the corresponding functional units are in a Function-Being-Processed State. When a command received from the host apparatus is provided for any one of the functional units, the controller transfers the command to the functional unit. In the case of a read command for the status register group, the controller transmits a status of the status register group to the host apparatus as a response.
