Figure 6-24. ISP – 8-bit Packed SYNC – Progressive Mode(1)(2)(3)(4)(5)

(1) The polarity of cam_pclk, cam_fld, cam_vs, and cam_hs are configurable.

(2) The image sensor must be connected to the lower data lines and the unused lines must be grounded. However, it is possible to shift the

data to 0, 2, or 4 data internal lanes. The bit configurations are: cam_d[11:4] or cam_d[7:0] in 8-bit packed mode.

(3) Optionally, the data write to memory can be qualified by the external cam_wen signal. 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. The polarity of

cam_fld is programmable.

(4) The camera module can pack 8-bit data into 16 bits. It doubles the maximum pixel clock. This mode can be particularly useful to transfer

a YCbCr data stream or compressed stream to memory at very high speed.

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