(GPIO_GCLK)

(SDA1)

(SPI_SCLK)

DO NOT USE these pins for anything other

than attaching an I2C ID EEPROM. Leave

unconnected if ID EEPROM not required.

(GPIO_GEN1)

These pins are reserved for HAT ID EEPROM.

(SPI_CE0_N)

(SCL1)

(SPI_MISO)

(GPIO_GEN2)

(GPIO_GEN6)

At boot time this I2C interface will be

interrogated to look for an EEPROM

that identifes the attached board and

allows automagic setup of the GPIOs

(and optionally, Linux drivers).

(GPIO_GEN4)

ID_SD and ID_SC PINS:

(SPI_MOSI)

(GPIO_GEN0)

(GPIO_GEN3)
