External synchronizing signal detection control.
Signal absent
→ signal present transition
detection.
Sets the sampling period in which SYNC can
be detected continuously in the horizontal
synchronizing signal period (1H).
Values in parentheses apply when RNE0
(COM18) is 1.
External synchronizing signal detection
control.
Signal present
→ signal absent transition
detection.
Sets the sampling period in which SYNC
cannot be detected continuously in the
horizontal synchronizing signal period (1H).
Note: All registers are set to 0 when the LC74775/M is reset by the RST pin.
