NOTES:
1. In a daisy-chain depth expansion, FL is held LOW for the "first load device". The RXI and WXI inputs are driven by the corresponding RXO and WXO outputs of the
2. In a daisy-chain depth expansion, FL is held HIGH for members of the expansion other than the "first load device". The RXI and WXI inputs are driven by the corresponding
