The device functional modes are shown in Figure 8-16.
- 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.
