FXOS8700CQR1 datasheet by Freescale Semiconductor

FXOS8700CQR1 Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the FXOS8700CQR1?
  The recommended power-on sequence is to power up the VDDIO pin first, followed by the VDD pin. This ensures that the internal voltage regulators are powered up correctly.
• How do I configure the FXOS8700CQR1 for low-power mode?
  To configure the FXOS8700CQR1 for low-power mode, set the LPEN bit in the CTRL_REG1 register to 1. This reduces the current consumption of the device.
• What is the purpose of the NO_OP command in the FXOS8700CQR1?
  The NO_OP command (0x00) is a no-operation command that can be used to synchronize the SPI interface or to insert a delay between commands.
• How do I handle the FXOS8700CQR1's interrupt output?
  The FXOS8700CQR1's interrupt output is an open-drain output, so it requires an external pull-up resistor to VDDIO. The interrupt output is active-low, so it is pulled low when an interrupt occurs.
• What is the maximum frequency for SPI communication with the FXOS8700CQR1?
  The maximum frequency for SPI communication with the FXOS8700CQR1 is 10 MHz.
