* Note:
HEX data is parallel input data which is represented by the 4- or 5-bit binary data listed in the column to the immediate right
of HEX data. Binary bits are listed from left to right in the following order.
8-Bit Mode: D7, D6, D5, D4, (4-Bit Binary), and D3, D2, D1, D0, (4-Bit Binary)
9-Bit Mode: D8, D7, D6, D5, D4, (5-Bit Binary), and D3, D2, D1, D0, (4-Bit Binary)
10-Bit Mode: D8, D7, D6, D5, D4, (5-Bit Binary), and D9,D3, D2, D1, D0, (5-Bit Binary)
Serial bits are shifted out with the most significant bit of the most significant nibble coming out first.
