REF EN: Internal Voltage Reference Enable
0 = Internal Voltage Reference Disabled
1 = Internal Voltage Reference Enabled (default)
REF HI: Internal Reference Voltage Select
0 = Internal Reference Voltage = 1.25V
1 = Internal Reference Voltage = 2.5V (default)
BUF EN: Buffer Enable
0 = Buffer Disabled
1 = Buffer Enabled (default)
BIT ORDER: Set Order Bits are Transmitted
0 = Most Significant Bit Transmitted First (default)
1 = Least Significant Bit Transmitted First
Data is always shifted into the part most significant
bit first. Data is always shifted out of the part most
significant byte first. This configuration bit only con-
trols the bit order within the byte of data that is
shifted out.
