D4 GPIO14 (SPI_MOSI) GPIO10 19 20
GPIO14 E2 GPIO15 (SPI_MISO) GPIO9 21 22 GPIO25 (GPIO_GEN6) These pins are reserved for ID EEPROM.
GPIO15 (SPI_SCLK) GPIO11 23 24 GPIO8 (SPI_CE0_N)
C1 GPIO16 25 26 GPIO7 (SPI_CE1_N) At boot time this I2C interface will be
GPIO16 E1 GPIO17 ID_SD 27 28 ID_SC interrogated to look for an EEPROM
GPIO17 B4 GPIO18 GPIO5 29 30 that identifes the attached board and
GPIO18 G8 GPIO19 GPIO6 31 32 GPIO12 allows automagic setup of the GPIOs
GPIO19 E5 33 34 (and optionally, Linux drivers).

GPIO21 B3 GPIO22 GPIO26 37 38 GPIO20 DO NOT USE these pins for anything other
GPIO22 C5 GPIO23 39 40 GPIO21 than attaching an I2C ID EEPROM. Leave
GPIO23 A4 GPIO24 unconnected if ID EEPROM not required.
