Function
Composite SYNC input pin to separate into
H- and V-SYNC.
Input the signal via a clamp capacitor.
Remark: SYNC1 IN is not available when
HD or VD input pin.
Input a separated horizontal or vertical sync
signal (1.0 to 2.0 Vp-p) via a resistor and a
coupling capacitor.
The polarity of the input signal is detected
and its leading edge becomes a timing
trigger.
Video signal output pin.
Refer to Bus Control Functions for the
output from each pin.
Audio signal output pin.
Refer to Bus Control Functions for the
output from each pin.
Video signal output pin for a monitor output.
Refer to Bus Control Functions for the
output from the pin.
HD or VD output pin.
The polarity of the output is selectable by
HV-POL register.
The tailing edge of the VD-OUT has a jitter.
Use the leading edge only.
A filter pin for sync detection.
Connect a capacitor between this pin and
GND.
A-SYNC = 1 (ON).
