CAUTION : Following DCMI signals are multiplexed with other
functions. In case CAMERA module is plugged, take care that the
corresponding features are disconnected or well configured :
DCMI_D0 : STMod+_INT
DCMI_D1 : DFDATIN3 (STMod+)
DCMI_D4 : PSRAM_A20 (only in case of U6 PSRAM is used)
DCMI_D6 : STMod+_PWM
DCMI_D7 : STMod+_RESET
DCMI_HSYNC/DE : STMod+_ADC and ARD_D7
CAMERA is exclusive with some STMod+ , PMOD and ARDUINO signals
