Register Name
Input format setting.
Selects H-sync higher threshold count number for the no-input detection.
Selects H-sync lower threshold count number for the no-input detection.
Selects the signal detection count number for input existence threshold of the
no-input detection.
Selects the signal detection count number 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 to 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.
The time constant of LPF for no-input detection is changed by this function and the
capacitor value of SYNC FILTER (pin10).
