PRODUCTION DATA.
The power-save mode (PSM) is enabled by setting PSM_EN to 1 in the function control register.
When powered on, the default value of this bit is 0. When this function is enabled, if all the GS data received for the next frame are 0, then device enters power-save mode during the display of the next frame. When the device is in power-save mode, it resumes normal mode when it detects non-zero GS data input. In power-save mode, part of analog circuits are not operational; the device total current consumption, ICC, is 1 mA(typical).
