Figure 6-23. ISP – 12-Bit SYNC Normal – Progressive Mode(1)(2)(3)(4)(5)(6)(7)(8)

(1) The polarity of cam_pclk, cam_fld, cam_vs, and cam_hs are configurable. If the cam_hs, cam_vs, and cam_fld signals are output, the

signal length can be set.

(2) The parallel camera in SYNC mode supports progressive image sensor modules and 8-, 10-, 11-, or 12-bit data.

(3) When the image sensor has fewer than 12 data lines, it must be connected to the lower data lines and the unused lines must be

grounded.

(4) However, it is possible to shift the data to 0, 2, or 4 data internal lanes.

(5) The bit configurations are: cam_d[11:4] or cam_d[7:0] in 8-bit mode, cam_d[11:2] or cam_d[9:0] in 10-bit mode, cam_d[10:0] in 11-bit

mode, and cam_d[11:0] in 12-bit mode.

(6) Optionally, the data write to memory can be qualified by the external cam_wen signal.

(7) The cam_wen signal can be used as a external memory write-enable signal. The data is stored to memory only if cam_hs, cam_vs, and

cam_wen signals are asserted.

(8) In cam_xclki; I is equal to a or b.
