Camera interface (DCMI) timing specifications
Unless otherwise specified, the parameters given in Table 106 for DCMI are derived
from tests performed under the ambient temperature, fHCLK frequency and VDD supply
voltage summarized in Table 17, with the following configuration:
•
DCMI_PIXCLK polarity: falling
•
DCMI_VSYNC and DCMI_HSYNC polarity: high
•
Data formats: 14 bits
