I have a simple question, i couldn't find in the datasheet. I want to use the BMA400 to set the BMA400 in Sleep mode so its power consumption goes down to 200 nA and i want to be able to wake it up from my µC. I saw, that the INT1 und INT2 are only outputs. Is there a way to wake the BMA up from the µC ?
Looking forward to your responses.
Thanks for your inquiry.
After power on BMA400 will be in suspend mode by default. Your uC can write value of 0x01 to register 0x19 to bring BMA400 to low power mode or write value of 0x02 to register 0x19 to bring BMA400 to normal mode. Please refer to section 4.3 on page 19 of BMA400 datasheet at https://www.bosch-sensortec.com/media/boschsensortec/downloads/datasheets/bst-bma400-ds000.pdf for more information.
