Register description

The device contains a set of registers which are used to control its behavior and to retrieve

angular rate data. The register address, consisting of 7 bits, is used to identify them and to

write the data through the serial interface.

7.1

OUT_X_L (03h), OUT_X_H (04h)

X-axis angular rate data. The value is expressed as two’s complement.

7.2

OUT_Y_L (05h), OUT_Y_H (06h)

Y-axis angular rate data. The value is expressed as two’s complement.

7.3

STATUS_REG (09h)

7.4

CTRL_REG1 (0Bh)

Table 11. STATUS_REG description

YXOR

X, Y-axis data overrun. Default value: 0

(0: no overrun has occurred; 1: new data has overwritten the previous data before it was

read)

XOR

X-axis data overrun. Default value: 0

(0: no overrun has occurred; 1: new data for the X-axis has overwritten the previous data)

YOR

Y-axis data overrun. Default value: 0

(0: no overrun has occurred; 1: new data for the Y-axis has overwritten the previous data)

YXDA

X, Y-axis new data available. Default value: 0

(0: a new set of data is not yet available; 1: a new set of data is available)

XDA

X-axis new data available. Default value: 0

(0: new data for the X-axis is not yet available; 1: new data for the X-axis is available)

YDA

Y-axis new data available. Default value: 0

(0: new data for the Y-axis is not yet available;1: new data for the Y-axis is available)
