Self test on the LIS2DE12TR

SShan.11
Associate II

Hello,

I am working on a project where I have to interface the LIS2DE12TR Accelerometer via I2C interface with TI cc2652 chip. As a start I wanted to verify the hardware functionality. In the datasheet it is mentioned of a Self-Test Mode of operation. I did not understand how the operation can be verified in the self-test. Should we just enter into self test mode and then monitor the x,y,z output values and check if they are within the specified range ? Also is there any example for this self test procedure that has been done.

Also in the datasheet there is mentioned a Slave Ack and a Master ACK. How do we know that the slave Ack has been received and how do we send a Master Ack/Nack

Regards,

SS
