am reading the registers with I2C multiple bytes, updating only the required bits and writing registers. So without power reset if i follow same sequence of reading again and updating only bit values (but writing full register values) then the outpu...

I have erased full chip using ST link utility. Programmed my application code and read the variables which are read from flash. In STlink utility it shows FF but in my code after read flash it shows 3784 for read32variable.

yes but I see the value 3784. I did full flash erase using STlink utility then downloaded my code and next power on just read those values it shown 3784 .

Thank you. I am using EPROM emulation library. EEinit function will check the state and it has erased the flash because of invalid state. But When I read the contents in code it shows 3784 . It should show FF but dont understand why it is showing 37...

Also, Can I know more about power down mode? I mean when we write ODR reg as 00 then it will go in power down mode but in power down mode any interrupt will be working or to wakeup from power down do we need to reconfig all registers again?

Thank you Eleon.I am not using FIFO mode and using bypass mode. My observation is during runtime if I read second time the registers , value of FIFO control register becomes 0x19 from 0x00. Is there any impact to these registers ? Also, second questi...

HI I am using 32f207 and eeprom emulation logic for storing data in flash. I like to know what will be values if we erase this flash memory? I am getting something like 3784 value read after erasing flash

Hi, I am using LIS3DH in one of the application. What will happen if you read the registers second time after writing the registers? I am reading the registers with I2C multiple bytes, updating only the required bits and writing registers.
