H COUNT MAX
Selects the H-sync count number for the higher threshold for the no-input detection.
0000: 32 counts
1111: 62 counts
(2 counts / step)
32 counts
(0000)
H COUNT MIN
Selects the H-sync count number for the lower threshold for the no-input detection.
000: 16 counts
111: 30 counts
(2 counts / step)
16 counts
(000)
SIG DET N
Selects the number of signal detections for the input existence threshold of the
no-input detection.
0000: 1 count
0001: 2 counts to 1111: 30 counts
(2 counts / step)
1 count
(0000)
SIG RESET N
Selects the number of signal detection for input non-existence threshold of the
no-input detection.
0000: 1 count
0001: 2 counts to 1111: 30 counts
(2 counts / step)
1 count
(0000)
SIG RESET
Resets the counter for no-input detection.
When 1 is sent, the counter for no-input detection is cleared at that time.
0: Normal
1: Reset
Normal
(0)
SIG SW
Selects the input to the counter for no-input detection.
0: SYNC2-IN (pin 15)
1: SYNC1-IN (pin 33)
SYNC2-IN
(0)
SIG DET IMPE
Changes the internal impedance for no-input detection.
The time constant of LPF for no-input detection is changed by this function and the
capacitor value of SYNC FILTER (pin 14).
