This register provides the controls for the respiration circuitry; see the Respiration section for details.
Bit 7
RESP_DEMOD_EN1: Enables respiration demodulation circuitry (ADS1294R/6R/8R only, for ADS1294/6/8 always
write '0')
This bit enables/disables the demodulation circuitry on channel 1.
0 = RESP demodulation circuitry turned off (default)
1 = RESP demodulation circuitry turned on
Bit 6
RESP_MOD_EN1: Enables respiration modulation circuitry (ADS1294R/6R/8R only, for ADS1294/6/8 always write '0')
This bit enables/disables the modulation circuitry on channel 1.
0 = RESP modulation circuitry turned off (default)
1 = RESP modulation circuitry turned on
Bit 5
Reserved
Must always be set to '1'
Bits[4:2]
RESP_PH[2:0]: Respiration phase(1)
These bits control the phase of the respiration demodulation control signal. (GPIO4 is out-of-phase with GPIO3 by the
phase determined by the RESP_PH bits.)
000 = 22.5
° (default)
001 = 45
°
010 = 67.5
°
011 = 90
°
100 = 112.5
°
101 = 135
°
110 = 157.5
°
111 = N/A
Bits[1:0]
RESP_CTRL[1:0]: Respiration control
These bits set the mode of the respiration circuitry.
00 = No respiration (default)
01= External respiration
10 = Internal respiration with internal signals
11 = Internal respiration with user-generated signals
(1)
RESP_PH[2:0] phase control bits only for internal respiration (RESP_CTRL = 10) and external respiration (RESP_CTRL = 01) modes
when the CONFIG4.RESP_FREQ[2:0] register bits are 000b or 001b.
