Register Name
Input format setting.
Selects the H-sync count number for the higher threshold for the no-input detection.
Selects the H-sync count number for the lower threshold for the no-input detection.
Selects the number of signal detections for the input existence threshold of the
no-input detection.
Selects the number of signal detection for input non-existence threshold of the
no-input detection.
Resets the counter for no-input detection.
Selects the input to the counter for no-input detection.
Changes the internal impedance for no-input detection.
Changes the threshold for no-input detection.
Test modes for shipping test. Set all zero.
Set the horizontal and vertical mode according to the format that is input.
When A-SYNC = ON mode, this setting is invalid.
When 1 is sent, the counter for no-input detection is cleared at that time.
The time constant of LPF for no-input detection is changed by this function and the
capacitor value of SYNC FILTER (pin 14).
