Devices Software Selection
Once a specific device is selected, a specific I
2
C address must be used to address the given device type. While each
device is initially programmed with a default I
2
C address, it is possible to overwrite this address. See the specific
device data sheets for more information.

Note:
1. This is the I2C_Address byte value programmed into the ATECC608A device.
Note that multiple devices can be enabled provided they have different I
2
C addresses. If multiple devices with the
same address are selected, a failure occurs due to a conflict on the I
2
C bus.
