STATUS
The channel status register contains a group of individ-
ual control bits and a loss-of-sync (LOS) flag bit. BLANK
(when set to 1) forces suppression of the OSD insertion
graphics, independent of the memory contents. ASYNC
(when set to 1) enables the SHRxxxx registers to be
updated by the host immediately; otherwise, they are
updated at the next complete video field. HINC (when
set to 1) enables autoincrement of the QPHORIZ regis-
ter after each host read/write to OSD memory. VINC
(when set to 1) enables autoincrement of QPLINEH/L
after each host read/write to OSD memory. The LOS flag
is useful in detecting the presence (or absence) of com-
posite video at the channel VIDIN_. LOS is a 1 if the
channel
’
s valid composite sync is lost for more than one
horizontal line period. It resets back to zero once a valid
sync pulse is detected.
