EFIELD is used when configured as a master. When EFIELD is set low, the Normal vsync* signal is
output on the VSYNC* pin. When EFIELD is set high, field ID information is output on the VSYNC*
pin (VSYNC* low for Field-1 and high for Field-2)
PAL625 is used when configured as a master. When PAL625 is set low, 525-line operation is
selected. When PAL625 is set high, 625-line operation is selected. This mode is set by automatic
detection when configured as a slave.
YCSWAP should normally be set to zero. When configured as a slave, this bit can be set high to
swap the luma and chroma samples, thus altering the pixel sequence with respect to the incoming
HSYNC* timing reference.
SETUP is normally low for the common video modes. The setup and scaling function is toggled
when this bit is high. When SETUP is low, the 7.5IRE setup is enabled for NTSC and PAL-M with
scaling amplified for a 92.5% black-to-white range. When SETUP is high, the 7.5 IRE setup is
disabled for NTSC and PAL-M with 100% black-to-white range scaling. Other PAL formats have
setup disabled with normal 100% scaling.
PALSA is normally low for the common video modes. South American video Standards can be
enabled by setting this bit high. For 525-line operation, the PALSA enables PAL-M for Brazil; in 625-
line operation, the PALSA enables PAL-Nc for Argentina.
