Description

X-axis gyroscope offset correction factor, upper word

The XG_BIAS_LWR (see Table 89 and Table 90) and XG_BIAS_

UPR (see Table 91 and Table 92) registers combine to allow users

to adjust the bias of the x-axis gyroscopes. The data format exam-

ples in Table 16 also apply to the XG_BIAS_UPR register, and the

data format examples in Table 19 apply to the 32-bit combination

of the XG_BIAS_LWR and XG_BIAS_UPR registers. See Figure 68

for an illustration of how these two registers combine and influence

the x-axis gyroscope measurements.

Y-axis gyroscope offset correction factor, upper word

The YG_BIAS_LWR (see Table 93 and Table 94) and YG_BIAS_

UPR (see Table 95 and Table 96) registers combine to allow users

to adjust the bias of the y-axis gyroscopes. The data format exam-

ples in Table 16 also apply to the YG_BIAS_UPR register, and the

data format examples in Table 19 apply to the 32-bit combination of

the YG_BIAS_LWR and YG_BIAS_UPR registers. These registers

influence the y-axis gyroscope measurements in the same manner

that the XG_BIAS_LWR and XG_BIAS_UPR registers influence the

x-axis gyroscope measurements (see Figure 68).

The ZG_BIAS_LWR (see Table 97 and Table 98) and ZG_BIAS_

UPR (see Table 99 and Table 100) registers combine to allow users

to adjust the bias of the z-axis gyroscopes. The data format exam-

ples in Table 16 also apply to the ZG_BIAS_UPR register, and the

data format examples in Table 19 apply to the 32-bit combination of

the ZG_BIAS_LWR and ZG_BIAS_UPR registers. These registers

influence the z-axis gyroscope measurements in the same manner

that the XG_BIAS_LWR and XG_BIAS_UPR registers influence the

x-axis gyroscope measurements (see Figure 68).

X-axis accelerometer offset correction, upper word

The XA_BIAS_LWR (see Table 101 and Table 102) and XA_BIAS_

UPR (see Table 103 and Table 104) registers combine to allow

users to adjust the bias of the x-axis accelerometers. The data

format examples in Table 33 also apply to the XA_BIAS_ UPR reg-

ister and the data format examples in Table 34 apply to the 32-bit

combination of the XA_BIAS_LWR and XA_BIAS_UPR registers.

See Figure 69 for an illustration of how these two registers combine

and influence the x-axis accelerometer measurements.
