Abstract:
1. A method for data access via an inter-integrated circuit (I2C) protocol, the method comprising: receiving an I2C read command at an I2C slave device from an I2C master device, the I2C read command being intended to read from an internal memory of the I2C slave device; in response to receiving the I2C read command to read from the internal memory of the I2C slave device, altering the I2C read command at the I2C slave device such that the I2C read command causes stored data to be read from a storage device, being external to the I2C slave device, in place of reading from the internal memory of the I2C slave device; wherein: receiving an I2C write command at the I2C slave device from the I2C master device, the I2C write command being intended to write to the internal memory of the I2C slave device; wherein the I2C write command includes master data and a slave device register address; and in response to receiving the I2C write command to write to the internal memory of the I2C slave device, altering the I2C write command at the I2C slave device such that the I2C write command causes the master data to write to the storage device, being external to the I2C slave device, in place of writing to the internal memory of the I2C slave device.
