Abstract
A communication apparatus having power saving mode includes memory circuit unit and DMA module. The memory circuit unit is used for storing instruction and data information to be executed by microcontroller (or control circuit) of communication apparatus, and the DMA module is used to backup the instruction and data information and store such information into a memory of an electronic device when the communication apparatus receives a broadcast synchronization signal periodically sent from another communication device. During the power saving mode, the memory circuit unit is powered down. When leaving the power saving mode, the memory circuit unit is powered on, and the DMA module retrieves the instruction and data information from the memory of the electronic device and write such information into the memory circuit unit.
