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, f_HCLK frequency and V_DD 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
