Bits[7:5]
RESP_FREQ[2:0]: Respiration modulation frequency
These bits control the respiration control frequency when RESP_CTRL[1:0] = 10 or RESP_CTRL[1:0] = 10(1).
000 = 64kHz modulation clock
001 = 32kHz modulation clock
010 = 16kHz square wave on GPIO3 and GPIO04. Output on GPIO4 is 180 degree out of phase with GPIO3.
011 = 8kHz square wave on GPIO3 and GPIO04. Output on GPIO4 is 180 degree out of phase with GPIO3.
100 = 4kHz square wave on GPIO3 and GPIO04. Output on GPIO4 is 180 degree out of phase with GPIO3.
101 = 2kHz square wave on GPIO3 and GPIO04. Output on GPIO4 is 180 degree out of phase with GPIO3.
110 = 1kHz square wave on GPIO3 and GPIO04. Output on GPIO4 is 180 degree out of phase with GPIO3.
111 = 500Hz square wave on GPIO3 and GPIO04. Output on GPIO4 is 180 degree out of phase with GPIO3.
Modes 000 and 001 are modulation frequencies in internal and external respiration modes. In internal respiration mode, the
control signals appear at the RESP_MODP and RESP_MODN terminals. All other bit settings generate square waves as
described above on GPIO4 and 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'
54
