11.12 OUTCFG: OUTPUT CONFIGURATION REGISTER
This register can be used to set the resolution of the accelerometer measurements, the
maximum g-range and low-pass filter settings for sampling and the bandwidth setting for the
GINT interrupt. The lowest 2 bits must be set by software to binary b‘11.

Accelerometer g Ranges and Resolution
00: Select +/- 2g range, 10-bit resolution
01: Select +/- 4g range, 10-bit resolution
10: Select +/- 8g range, 10-bit resolution
11: Select +/- 8g range, 14-bit resolution
Low Pass Filter bandwidth
000: Low-pass filter set to 512 Hz bandwidth
001: Low-pass filter set to 256 Hz bandwidth
010: Low-pass filter set to 128 Hz bandwidth
011: Low-pass filter set to 64 Hz bandwidth
100: Low-pass filter set to 32 Hz bandwidth
101: Low-pass filter set to 16 Hz bandwidth
110: Low-pass filter set to 8 Hz bandwidth
111: Reserved
GINT sample rate trigger
0: GINT interrupt updates at sample acquisition rate
1: GINT interrupt updates at LPF bandwidth setting determined by LPF[2:0]
If IRATE=’1’, the GINT interrupt will occur at the same rate as the bandwidth setting
of the LPF. This prevents extraneous sample acquisition interrupts at a rate greater
than the LPF setting.
