TDA9115
(start of vertical sawtooth ramp on the VOut
pin)
1: Permanent blanking - high blanking level in
composite signal on pin HLckVBk is per-
manent
Sad17/D1 - VOutEn
Vertical Output Enable
0: Disabled, VoffVOut on VOut pin (see 6.5
Vertical section)
1: Enabled, vertical ramp with vertical position
offset on VOut pin
Sad17/D2 - HBOutEn
Horizontal and B+ Output Enable
0: Disabled, levels corresponding to “power
transistor off” on HOut and BOut pins (high
for HOut, high or low for BOut, depending
on BOutPol bit).
1: Enabled, horizontal deflection drive signal
on HOut pin providing that it is not inhibited
by another internal event (activated XRay
protection). B+ drive signal on BOut pin.
Programming the bit to 1 after prior value of 0,
will initiate soft start mechanism of horizontal
drive and of B+ DC/DC convertor
Sad17/D3 - BOHEdge
Selection of Edge of Horizontal drive signal to
phase B+ drive Output signal on BOut pin. Only
applies if the bit BOutPh is set to 1, otherwise
BOHEdge has no effect.
0: Falling edge
1: Rising edge
Sad17/D4,D5,D6,D7 - THM, TVM, TH, TV
Test bits. They must be kept at 0 level by appli-
cation S/W.
