IMAGE FORMING APPRATUS, MICROCONTROLLER, AND METHODS FOR CONTROLLING IMAGE FORMING APPARATUS AND MICROCONTROLLER |
摘要 |
A microcontroller are provided. The microcontroller include: a memory controller which is connected to an external memory operating in a self-refresh mode if a normal mode changes to a low power mode, performs a control operation by using the external memory in the normal mode, and outputs a preset signal which is to cancel the self-refresh mode if the low power mode changes to the normal mode, a memory interface unit which transmits the preset signal to a main memory, and a signal detector which detects whether the preset signal has been output. Here, the memory controller powers off the memory interface unit if the normal mode changes to the low power mode and powers on the memory interface unit if the low power mode changes to the normal mode, and the output of the preset signal is detected by the signal detector. |
