Camera interface (DCMI) timing specifications
Unless otherwise specified, the parameters given in Table 108 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
Capacitive load C = 30 pF
Measurement points are done at CMOS levels: 0.5 VDD
