MMA8453Q accelerometer with I2C

[mezri]

hello

Following testing of an MMA8453Q accelerometer with I2C, it's been noted that all registers consistently yield either 0xFF or 0x00. However, the expected value of register CTRL_REG1 is 0x19. Could someone provide insight into why this discrepancy is occurring and suggest potential solutions?
