FUNCTIONAL DESCRIPTION
MODE configuration
SeeTable 1 to Table 3 for details.
master = 1: master mode
master = 0: slave mode
Horizontal sync and vertical sync are generated from internal timing and are output at the rising edge of
clk_27.
md[3]: Defines EFIELD function
md[2]: Defines PAL625 function
Horizontal sync and vertical sync are inputs that are synchronized by clk_27.
A falling edge of VSYNC* occurring within ±1/4 of a scan line from the falling edge of HSYNC* cycle time
indicates the beginning of Field-1. A falling edge of VSYNC* occurring within ±1/4 of a scan line from the
middle point of the line indicates the beginning of Field-2. See Figure 2.
md[3]: Defines YCSWAP
md[2]: Defines SETUP function
md[1]: Defines PALSA function, South America.
0: vsync is output pin
