HD1-INV (HD1 output polarity switch)
HD2-INV (HD2 output polarity switch)
V-FREQUENCY (Vertical frequency switch (pull-in range))
CLP PHS (Clamp pulse phase switch)
FREQ DET SW (Horizontal/vertical frequency counter switch)
INPUT SW (Input signal switch for synchronization)
HD PHASE (HD phase adjustment)
VD1-INV (VD1 output polarity switch)
VD2-INV (VD2 output polarity switch)
Switches HD1 output (pin 13) polarity. When set to 0, positive HD input is output as negative HD. When
set to 0, output from the sync circuit is output as negative HD.
Switches HD1 output (pin 15) polarity. When set to 0, positive HD input is output as negative HD. When
set to 0, output from the sync circuit is output as negative HD.
Sets vertical frequency pull-in range, VD-STOP, or free-running frequency.
Free-running frequency is controlled by H-FREQUENCY.
Switches clamp pulse phase.
If no signal input, 0.9 µs pulse is output from the H-C/D circuit.
Switches input signal used for horizontal/vertical frequency counter. This switch is controlled
independently from INPUT SW. The detection result is output as read BUS data.
Switches input signal used for synchronization.
Adjusts phase of HD output from the sync circuit. The phase of the adjustment center value is the same
as that of input H-SYNC or input HD. (Note) Synchronized VD width will change, when HD PHASE will
be changed.
Switches VD1 output (pin 22) polarity. When set to 0, negative VD input is output as negative VD. When
set to 0, output from the sync circuit is output as negative VD.
Switches VD2 output (pin 23) polarity. When set to 0, negative VD input is output as negative VD. When
set to 0, output from the sync circuit is output as negative VD.
