This switches the LPF circuit on and off.
This switches the trap circuit on and off.
This adjusts the DA output voltage. Adjustment from LSB
Set this according to the input signal level.
This switches between internal sync separation and external sync signal input.
This switches the input signal.
This performs the power saving setting. Be sure to use this setting as described in “Power supply and power
saving sequence”. The power-on default for this IC is power saving mode, so the settings should be canceled by
serial communication after power-on. The LCD panel power supply must be turned off in power saving mode.
