PROCESSING SENSOR DATA
Table 8 provides a summary of the output data registers, which
use the bit pattern shown in Figure 14. The ND bit is equal to 1
when the register contains unread data. The EA bit is high when
any error/alarm flag in the DIAG_STAT register is equal to 1.

Assumes that the scaling is set to ±320°/sec. This factor scales with the range.
0x0000 = 25°C (±5°C).
For the ±320°/sec setting, rate values scale with the range setting.

OPERATIONAL CONTROLS
Internal Sample Rate
The SMPL_PRD register controls the internal sample rate using the
bit assignments in Table 14. When SMPL_PRD[7:0] = 0x00, the
internal sample rate is 2048 SPS. When SMPL_PRD[7:0] ≥ 0x01,
use the bit definitions in Table 14 and the following equation to
calculate the sample rate.
