Function

Pace 3 detected

Pace 3 detected. This bit is set once a pace pulse is detected. This bit is set on the

trailing edge of the pace pulse.

0 = pace pulse not detected in current frame.

1 = pace pulse detected in this frame.

[22:20]

Pace Channel 3 width

This bit is log2 (width) − 1 of the pace pulse.

Width = 2N + 1/128 kHz.

0000

[19:16]

Pace Channel 3 height

This bit is the log2 (height) of the pace pulse.

Height = 2N × VREF/gain/216.

Pace 2 detected

Pace 2 detected. This bit is set once a pace pulse is detected. This bit is set on the

trailing edge of the pace pulse.

0 = pace pulse not detected in current frame.

1 = pace pulse detected in this frame.

000

[14:12]

Pace Channel 2 width

This bit is log2 (width) − 1 of the pace pulse.

Width = 2N + 1/128 kHz.

0000

[11:8]

Pace Channel 2 height

This bit is the log2 (height) of the pace pulse.

Height = 2N × VREF/gain/216.

Pace 1 detected

Pace 1 detected. This bit is set once a pace pulse is detected. This bit is set on the

trailing edge of the pace pulse.

0 = pace pulse not detected in current frame.

1 = pace pulse detected in this frame.

000

[6:4]

Pace Channel 1 width

This bit is log2 (width) − 1 of the pace pulse.

Width = 2N + 1/128 kHz.

0000

[3:0]

Pace Channel 1 height

This bit is the log2 (height) of the pace pulse.

Height = 2N × VREF/gain/216.

If using 128 kHz data rate in frame mode, this word is stretched over two 16-bit words. If using the 128 kHz data rate in regular read/write mode, all 32 bits are sent.

Log data for width and height is provided here to ensure that it fits in one full 32-bit data-word. As a result, there may be some amount of error in the resulting value.

For more accurate reading, read the 0x3A, 0x3B, 0x3C registers (see Table 52).

ADAS1000-4 model only, ADAS1000-3 model does not contain these features.

Respiration Magnitude[23:0]

Magnitude of respiration signal. This is an unsigned value.

4 × (VREF/(1.6468 × respiration gain))/(224 – 1).

If using 128 kHz data rate in frame mode, this word is stretched over two 16-bit words. If using the 128 kHz data rate in regular read/write mode, all 32 bits are sent.

ADAS1000-4 model only, ADAS1000-3 model does not contain these features.

[23:0]

Respiration

Phase[23:0]

Phase of respiration signal. Can be interpreted as either signed or unsigned value. If

unsigned, the range is from 0 to 2π. If signed, the range is from – π to +π.

0x000000 = 0.

0x000001 = 2π/224.

0x400000 = π/2.

0x800000 = +π = − π.

0xC00000 = +3π/2 = − π/2.

0xFFFFFF = +2π(1 − 2−24) = −2π/224.

This register is not part of framing data, but may be read by issuing a register read command of this address.

ADAS1000-4 model only, ADAS1000-3 model does not contain these features.
