LIS331DLH issue disabling self-test mode

Discussion created by Steven Eckhart on Aug 29, 2017



I have noticed that from time to time if self-test mode is enabled, when I write to CTRL_REG4 register to disable self-test mode the register does not update. There is no indication of a bus error and all communication seems to be working. A retry seems to result in the register being updated but nonetheless has anyone run into a case where writing to a register fails without an error indication?
