Bit 7
FLAG: Out-of-range flag
0 = Disabled (default)
1 = Enabled: replaces bit 24 (LSB) of the conversion data with the out-of-range bit; if the
CHKSUM byte is enabled, bit 7 of the checksum byte
Bit 6
CHKSUM: Checksum
0 = Disabled (default)
1 = Conversion data checksum byte included in readback
Bit 5
Reserved
Always write '0'.
