HLOCKN - Horizontal lock
This bit indicates whether the
horizontal oscillator in the sync
processor is locked to the video
signal. When the oscillator is locked
HLOCKN is set to logic 0
not locked HLOCKN is set to logic 1
HCENT - Horizontal centre
This bit is set to logic 0 when the
horizontal oscillator frequency is too
high (V

HEX
A write operation starts with address
byte 100011Ao0. The device is then
ready to receive the subaddress byte
e.g. trapezium (HEXOA) 00001010
followed by the data byte e.g. HEX20.
The DAC will then set the trapezium
correction signal into the selected
position (see Fig.5). If more data
bytes follow within one transmission
then, by means of an auto-increment,
the next highest subaddress will be
selected. Wrap-around occurs after
HEXOF.
