8.4 Device Functional Modes
The device functional modes are shown in Figure 8-16.
Figure 8-16 Functional Modes- Initialization: the device enters into Initialization when Vcc goes down to UVLO voltage. In this mode, all the registers are reset. Entry can also be from any state.
- Normal: the device enters the normal mode when Vcc is higher than UVLO threshold. The display process is shown as below in normal mode.
- Power saving: the device automatically enters and gets out from the power save mode when it detects the condition PSin and PSout. In this mode, all channels turn off. PSin: after the device detects that the display data of the next frame all equal to zero, it enters to power save mode when the VSYNC comes. PSout: after the device detects that there is non-zero display data of the next frame, it gets out from power save mode immediately.
- IREF Resistor Short Protection: the device automatically enters and gets out from the IREF resistor short protection mode when it detects the condition ISPin and ISPout. In this mode, all channels turn off. ISPin: the device detects that the reference voltage is smaller than 0.195 V ISPout: the device detects that the reference voltage is larger than 0.325 V.
- Thermal Shutdown: the device automatically enters and gets out from the thermal shutdown mode when it detects the condition TSDin and TSDout. In this mode, all channels turn off. TSDin: the device detects that the junction temperature exceeds 170° C TSDout: the device detects that the junction temperature is below 155° C.
