Store X-axis acceleration data to ring buffer
1 – enabled
0 – disabled
Store Y-axis acceleration data to ring buffer
1 – enabled
0 – disabled
Store Z-axis acceleration data to ring buffer
1 – enabled
0 – disabled
Additional data rate reduction after calibration
before data is loaded to ring buffer (no effect on
output registers data rate, see section 2.5.1)
11 – No rate reduction
10 – divide rate by 4
01 – divide rate by 2
00 – No rate reduction
Description
Lock can be opened by writing the following
sequence into this register:
00h, 50h, A0h Writing any other sequence closes the
lock. Lock state can be read from STATUS register.
Description
Interrupt when output ring buffer is ¾ full
1 – Enabled
0 – Disabled
Interrupt when output ring buffer is ½ full
1 – Enabled
0 – Disabled
Reserved
Mask all interrupts (only effects on the INT-pin)
1 – Mask all interrupts (including free fall
0 – Mask interrupts according to configured mode
INT-pin signal activity
1 – INT active high (INT-pin high)
0 – INT active low (INT-pin low)
Description
Data bits [7:0] of selected 8-bit control register. Write
this register to actually perform the write operation to
selected location. See register CTRL_SEL for
information on register contents.
