7.5.3.1 Chip Index Write Command

The chip index is used to set the identification of the device cascaded in a data chain. When the first device receives the chip index command Head_bytes1, it sets the current address to 00h and meanwhile change the chip index command Head_bytes2, then sends to the next device. When the device receives the Head_bytes2, it sets the address to 01h and meanwhile changes the chip index command Head_bytes3, then sends to the next device, likewise, all the cascaded devices get their unique identifications.
