Bits [7:5]
RESP_FREQ[2:0]: Respiration control frequency
These bits control the respiration control frequency when RESP_CTRL[1:0] = 10(1).
000 = 64kHz (GPIO4 is out-of-phase with GPIO3 by the frequency determined by the RESP_PH bits)
001 = 32kHz (GPIO4 is out-of-phase with GPIO3 by the frequency determined by the RESP_PH bits)
010 = 16kHz (GPIO4 is 180° out-of-phase with GPIO3)
011 = 8kHz (GPIO4 is 180° out-of-phase with GPIO3)
100 = 4kHz (GPIO4 is 180° out-of-phase with GPIO3)
101 = 2kHz (GPIO4 is 180° out-of-phase with GPIO3)
110 = 1kHz (GPIO4 is 180° out-of-phase with GPIO3)
111 = 500Hz (GPIO4 is 180° out-of-phase with GPIO3)
(1)
These frequencies assume fCLK = 2.048MHz.
Bit [4]
Must always be set to '0'
Bit [3]
SINGLE_SHOT: Single-shot conversion
This bit sets the conversion mode.
0 = Continuous conversion mode (default)
1 = Single-shot mode
Bit [2]
WCT_TO_RLD: Connects the WCT to the RLD
This bit connects WCT to RLD.
0 = WCT to RLD connection off (default)
1 = WCT to RLD connection on
Bit [1]
PD_LOFF_COMP: Lead-off comparator power-down
This bit powers down the lead-off comparators.
0 = Lead-off comparators disabled (default)
1 = Lead-off comparators enabled
Bit [0]
Must always be set to '0'
