LSB
Least Significant Byte is shown first when representing a multi-byte number as a
sequence of bytes. For example, the number 0x55AAFF00 is stored or specified
as 4 bytes 0x00, 0xFF, 0xAA, and 0x55.
MSB
Most Significant Byte is shown first when representing a multi-byte number as a
sequence of bytes. For example, the number 0x55AAFF00 is stored or specified
as 4 bytes 0x55, 0xAA, 0xFF, and 0x00.
FTxxx Refers to the FT232R, FT245R, FT232B, FT245B and FT2232D/L/C chips.
