Restart conversion
1: Restart conversion.
Bit Description
-
The System Calibration registers (CHx_SCAL_OFFSET and CHx_SCAL_GAIN) are:
0 (default): preserved even when "REG_AND_CNV_ RST" = 0xC3.
1: reset by setting "REG_AND_CNV_ RST" = 0xC3.
External clock detection
0 (default): "External Clock Detection" is operational
1: "External-Clock Detection" is bypassed
Clock select – only valid if CLK_EXT_DET = 1
0 (default): Selects internal clock
1: Selects external clock
Selects RTD Current as follows:
0x0 (default): 0 µA
0x1: 100 µA
0x2: 200 µA
0x3: 300 µA
0x4: 400 µA
0x5: 500 µA
0x6: 600 µA
0x7: 700 µA
0x8: 800 µA
0x9: 900 µA
0xA: 1000 µA
