HSYNC
Horizontal Sync Output. This signal indicates the beginning of a new line of
video. This signal is typically 64 CLKx1 clock cycles wide, and can be
programmed through HSLEN register. The falling edge of this output
indicates the beginning of a new scan line of video.
Note: The polarity of this pin is programmable through the POLARITY
register.
79
O,
LVTTL
VSYNC
Vertical Sync Output. This signal indicates the beginning of a new field of
video. This signal is output coincident with the rising edge of CLKx2, and is
normally six lines wide. The falling edge of VSYNC indicates the beginning
of a new field of video.
Note: The polarity of this pin is programmable through the POLARITY
register.
83
O,
LVTTL
HACTIVE
Active Video Output. This pin can be programmed to output the composite
active or horizontal active signal via the Hactive register. It is a logical high
