Description
TIMING SIGNAL OUTPUT
Signal levels are LVCMOS/LVTTL compatible.
Selectable timing output.
Selectable from: H sync; H blanking; V sync; V blanking; F sync; F
digital; Display Enable; 10 field ID (film cadence); AFS video/audio timing
(GS4911B only); USER_1~4.
See Section 1.5 on page 25 for signal descriptions.
NOTE: Default output is H blanking.
The current drive capability of this pin may be set high or low via
designated registers in the host interface. By default, the current drive
will be low.
This signal will be high impedance when VID_STD[5:0] = 00h.
