ABSTRACT:
An electronic device includes a serial interface which exchanges data with a memory register and a first data buffer. In accordance with a setting which is written in the memory register, data in the first data buffer is exchanged with a memory through a memory controller. The serial interface exchanges data with an add-on register and a second data buffer. In accordance with a setting which is written in the add-on register, data in the second data buffer is exchanged with an add-on unit through an add-on controller. The add-on unit is connected to an external LAN or the like. Part of the setting data written in the memory register and the add-on register is determined from the add-on unit by a system control circuit. In accordance with the determination, a function to be executed by the electronic device is changed.
