LPC1347FBD48,151 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 72 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 BODCR register to the desired voltage threshold and enable the BOD interrupt in the NVIC.
• What is the minimum voltage required for the ADC to operate correctly?
  The minimum voltage required for the ADC to operate correctly is 2.4 V.
