In addition to the 128 rows of windows, the AE/AWB module provides support for an additional row of windows for black data. This data may be useful in determining the DC offset noise of the rest of the data. The black row of windows can be before or after the regular rows of windows. The vertical start line for the black row of windows is specified in the H3A_AEWINBLK[27:16] WINSV bit field, and the height is specified in the H3A_AEWINBLK[6:0] WINH bit field. The horizontal starting pixel and horizontal width of the black row of windows are the same as for the regular rows of windows.
Figure 9-119 shows a black row of windows before rows of windows.
Table 9-197 lists the bit fields that configure the window and block sizes, counts, and starting positions.
Bit Field | Bit Width | Description |

H3A_AEWWIN1[20:13] WINW | 7 | Window width (in pixels) |
H3A_AEWWIN1[31:24] WINH | 7 | Window height (in lines) |
H3A_AEWWIN1[5:0] WINHC | 6 | Window count for horizontal direction |
H3A_AEWWIN1[12:6] WINVC | 7 | Window count for vertical direction |
H3A_AEWINSTART[11:0] WINSH | 12 | Window start position H |
H3A_AEWINSTART[27:16] WINSV | 12 | Window start position V |
H3A_AEWSUBWIN[3:0] AEWINCH | 4 | Horizontal distance between subsamples |

H3A_AEWINBLK[27:16] WINSV | 12 | Window start position H for single black line |
H3A_AEWINBLK[6:0] WINH | 7 | Window height (in lines) for single black line |
