A17 NANDF_CS2 CCM_CLKO2 CLK_OUPUT USB_CLK Clock a 24mhz x l'hub usb2514
F15 NANDF_CS0 GPIO6_IO11 output, HIGH level EN_VTT It turns off the Vtt when it goes in suspend mode, active high
B18 NANDF_D5 GPIO2_IO05 OUTPUT, open drain level (high) SDIO_PWR It enables the supply voltage of the sdcard, active high
D19 SD4_DAT7 GPIO2_IO15 OUTPUT, open drain level (low) SELUSB_HOST_nDEV USB selection of SAM3X8E in host or client mode , 0=host
D19 CSI0_DAT19 GPIO6_IO05 OUTPUT, low level CAM_RST Reset for the CSI camera module
P24 DISP0_DAT0 GPIO4_IO21 INPUT (piloted by driver) ERASE Cancellation of the SAM3X8E device before a reprogram, level 1 actives the cancellation, then it should be put in open drain
M6 CSIO_DAT18 GPIO6_IO04 OUTPUT, low level CAM_EN Enabling the CSI camera module, active high
P1 CSIO_PIXCLK GPIO5_IO18 INPUT DTR_ARD Monitoring the Arduino serial protocol to recognize erase and reset commands
L3 CSIO_DAT17 GPIO6_IO03 INPUT RTS_ARD Monitoring the Arduino serial protocol to recognize erase and reset commands
A19 NANDF_D4 GPIO2_IO04 OUTPUT, low level EN_5V It turns off the TENSION of 5VDC for the times it goes in suspend mode, active high
G25 EIM_A19 GPIO2_IO19 OUTPUT, open drain (low) WP_SPI_FLASH Logical level 1 = not protected 0= flash protected against scripts
