LPC11E68JBD100E Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the internal oscillator?
  The maximum clock frequency that can be used with the internal oscillator is 12 MHz.
• How do I configure the pin multiplexing to use the I2C interface?
  To configure the pin multiplexing for I2C, set the PINSEL0 register to select the I2C function for the desired pins (e.g. P0.27 for SCL and P0.28 for SDA).
• What is the maximum current that can be sourced or sunk by the GPIO pins?
  The maximum current that can be sourced or sunk by the GPIO pins is 4 mA.
• How do I enable the brown-out detection (BOD) feature?
  To enable the BOD feature, set the BODCTRL register to enable the BOD and set the desired voltage threshold.
• What is the minimum and maximum voltage range for the ADC?
  The minimum voltage range for the ADC is 0V and the maximum voltage range is VDDA (typically 3.3V).
