If sustained motion is detected (for example, continuous
shaking of the board), the
event and switches automatically to full bandwidth
measurement mode, as shown in Figure 18.
Figure 18. Sustained Motion Trigger Activity Interrupt
Following this sustained motion event, if the board remains
stable for more than its specified time (it is 3016 ms in the
example), the device returns to wake-up mode automatically, as
shown in Figure 19.

CONFIGURATION TAB

The Configuration tab allows the user to set the operating
conditions for the ADXL372, as well as read/write the contents

ADXL372 recognizes the activity
EVAL-ADXL372Z-M
The following actions are available in the Configuration tab:
• Set V
sets the main voltage of the ADXL372. The default
S
value is 2.5 V. When the Set V
applies the desired supply voltage and then reads back the
ADXL372 operating voltage, interface voltage, and current
consumption.
• Set VDD I/O sets the interface voltage of the ADXL372.
The default value is 2.4 V. When the Set VDD I/O button
is clicked, the ISEB applies the desired interface voltage,
and then reads back the
interface voltage, and current consumption.
• Write Target Register performs a write to a register. To
write a value to a register, select the register from the Write
Target Register menu and click the D7 through D0
indicators to set the value. When an indicator is lit, the
value written to that bit is Logic 1. When the indicator is
unlit, the value written to that bit is Logic 0. When the
register is configured correctly, click the Write Target
Register button to send the value to the ADXL372. Note
that the D7 through D0 indicators in the Write Target
Register are not updated based on the value stored in that
register.
Read Target Register performs as a read from a register.
•
To read a value from a register, select the register from the
Read Target Register menu and click the Read Target
Register button. The indicators in the Register Read box
refresh to reflect the target register content.
• Read All Registers performs a readback of the entire
ADXL372 memory map. Clicking Read All Registers
updates all register values and indicators on the right side
of the screen.
