Bit Descriptions for Sync Bits Bit Name Settings Description Reset Access [7:3] Reserved Reserved. 0x0 R 2 EXT_CLK Enable external clock. 0x0 R/W [1:0] EXT_SYNC Enable external sync control. 0x0 R/W 00 Internal sync. 01 External sync, no interpolation filter. After synchronization, and for EXT_SYNC within specification, DATA_RDY occurs on EXT_SYNC. 10 External sync, interpolation filter, next available data indicated by DATA_RDY 14 to 8204 oscillator cycles later (longer delay for higher ODR_LPF setting), data represents a sample point group delay earlier in time. 11 Reserved. I2C SPEED, INTERRUPT POLARITY, AND RANGE REGISTER Address: 0x2C, Reset: 0x81, Name: Range Table 47. Bit Descriptions for Range Bits Bit Name Settings Description Reset Access 7 I2C_HS I2C speed. 0x1 R/W 1 = high speed mode. 0 = fast mode. 6 INT_POL Interrupt polarity. 0x0 R/W 0 INT1 and INT2 are active low. 1 INT1 and INT2 are active high. [5:2] Reserved Reserved. 0x0 R [1:0] Range Range. 0x1 R/W 01 ±2 g. 10 ±4 g. 11 ±8 g. POWER CONTROL REGISTER Address: 0x2D, Reset: 0x01, Name: POWER_CTL Table 48. Bit Descriptions for POWER_CTL Bits Bit Name Settings Description Reset Access [7:3] Reserved Reserved. 0x0 R 2 DRDY_OFF Set to 1 to force the DRDY output to 0 in modes where it is normally signal data ready. 0x0 R/W 1 TEMP_OFF Set to 1 to disable temperature processing. Temperature processing is also disabled when STANDBY = 1. 0x0 R/W 0 STANDBY Standby or measurement mode. 0x1 R/W 1 Standby mode. In standby mode, the device is in a low power state, and the temperature and acceleration datapaths are not operating. In addition, digital functions, including FIFO pointers, reset. Changes to the configuration setting of the device must be made when STANDBY = 1. An exception is a high-pass filter that can be changed when the device is operating. 0 Measurement mode. |
