8.5.3.3 MPSM Write Command

The MPSM command is used to control the intelligent power save mode of devices in the same matrix. The device detects all zero data in a stackable module and receives MPSM command in current frame, then when VSYNC command comes, all devices in the same matrix turn off. After the device detects that there is non-zero display data of the next frame, it gets out from intelligent power save mode until MSPM command comes in current frame.
