CAMERA CONTROL INTERFACE SLEEP AND WAKE UP SIGNALING |
摘要 |
A device is provided comprising a control data bus including at least a first line. A master device may be coupled to the control data bus and configured to control the control data bus. A plurality of slave devices may be coupled to the control data bus and share the first line. The master device may be configured to send a single global wake up signal on the control data bus that causes any sleeping slave devices to wake up. Alternatively, the master device may send a global wake up signal followed by a targeted sleep signal to non-targeted slave devices to implement a “targeted wake up” of specific slave devices. The master device may send the single global wake up signal by bringing the first line low for a predetermined period of time. |
