Capture
Capture:
Setting a 1b in this register causes the internal processor to capture the current settings of the AGC status
and the vertical line count registers. Since this capture is not immediate, it is necessary to check for completion
of the capture by reading the capture bit repeatedly after setting it and waiting for it to be cleared by the internal
processor. Once the capture bit is 0b, the AGC status and vertical line counters (3Ch/3Dh and 9Ah/9Bh) have
been updated and can be safely read in any order.

Vertical line [9:8]
Vertical line [9:0] represents the detected a total number of lines from the previous frame. This can be used
with nonstandard video signals such as a VCR in trick mode to synchronize downstream video circuitry.
Since this register is a double-byte register, it is necessary to capture the setting into the register to ensure
that the value is not updated between reading the lower and upper bytes. In order to cause this register to
capture the current settings, bit 0 of the status request register (subaddress 97h) must be set to a 1b. Once
the internal processor has updated and can be read. Either byte may be read first since no further update will
occur until bit 0 of 97h is set to 1b again.
