Vertical line [9:0]:
Represent 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.
Because 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. 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 occurs until bit 0 of 97h is set to 1b again.
