DESCRIPTION
EFS
0
frame sync signal at pin FSVGC ignored in slave mode
1
frame sync signal at pin FSVGC accepted in slave mode
PCBN
0
normal polarity of CBO signal (HIGH during active video)
1
inverted polarity of CBO signal (LOW during active video)
SLAVE
0
the SAA7102; SAA7103 is timing master to the graphics controller
1
the SAA7102; SAA7103 is timing slave to the graphics controller
ILC
0
if hardware cursor insertion is active, set LOW for non-interlaced input signals
1
if hardware cursor insertion is active, set HIGH for interlaced input signals
YFIL
0
luminance sharpness booster disabled
1
luminance sharpness booster enabled
HSL
0
normal trigger event handling of the horizontal state machine, if the SAA7102;
SAA7103 is slave to HSVGC input
1
trigger event for horizontal state machine is shifted 128 PIXCLKs in advance, adapted
to a late HSVGC in slave mode

DESCRIPTION
HFS
0
horizontal sync is directly derived from input signal (slave mode) at pin HSVGC
1
horizontal sync is derived from a frame sync signal (slave mode) at pin FSVGC (only if
EFS is set HIGH)
VFS
0
vertical sync (field sync) is directly derived from input signal (slave mode) at
pin VSVGC
1
vertical sync (field sync) is derived from a frame sync signal (slave mode) at
pin FSVGC (only if EFS is set HIGH)
OFS
0
pin FSVGC is switched to input
1
pin FSVGC is switched to active output
PFS
0
polarity of signal at pin FSVGC in output mode (master mode) is active HIGH; rising
edge of the input signal is used in slave mode
1
polarity of signal at pin FSVGC in output mode (master mode) is active LOW; falling
edge of the input signal is used in slave mode
OVS
0
pin VSVGC is switched to input
1
pin VSVGC is switched to active output
PVS
0
polarity of signal at pin VSVGC in output mode (master mode) is active HIGH; rising
edge of the input signal is used in slave mode
1
polarity of signal at pin VSVGC in output mode (master mode) is active LOW; falling
edge of the input signal is used in slave mode
