Figure 25. Frame Period Measured in Clocks
Row Period (TROW)
line_length_pck will determine the number of clock
periods per row and the row period (TROW) when combined
with the sensor readout clock. line_length_pck includes both
the active pixels and the horizontal blanking time per row.
The sensor utilizes two readout paths, as seen in Figure 1,
allowing the sensor to output two pixels during each pixel
clock.
Row Periods Per Frame
frame_length_lines determines the number of row periods
(TROW) per frame. This includes both the active and
blanking rows. The minimum vertical blanking value is
defined by the number of OB rows read per frame, two
embedded data rows, and two blank rows.

The sensor is configured to output frame information in
two embedded data rows by setting R0x3064[8] to 1
(default). If R0x3064[8] is set to 0, the sensor will instead
output two blank rows. The data configured in the two
embedded rows is defined in two embedded rows of data at
the top of the frame by setting R0x3064[7] and two rows of
embedded statistics at the end of the frame by setting
R0x3064[7] for exposure calculations. See the section on
Embedded Data and Statistics.

The locations of the OB rows, embedded rows, and blank
rows within the frame readout are identified in Figure 26:
