The MitySOM-335x module can support up to 3 Inter-Integrated Circuit (I2C) ports.

• I2C0 [ Edge connector ]

• No pull-up resistors on module
• No pre-defined uses

• I2C1 [ Edge connector ]

• Pull-up reistors installed on module
• Factory configuration EEPROM (address 1010XXXb - hex 0x50 to 0x57)
• PMIC SmartReflex interface(address 0101101b - hex 0x12)

• I2C2 [Not available on the edge connector]

• PMIC Peripheral interface(address 0010010b - hex 0x2D)

The MitySOM-335x module can support up to 2 Serial Peripheral Interface (SPI) ports:

• SPI0 [ Edge Connector ]

• No pre-defined uses

• SPI1 [ Edge Connector ]

• Modules WITH NOR memory use SPI1 CS0 for the NOR, CS1 is available
• Modules without the NOR memory have both CS0 and CS1 available.
