LPC2214FBD144/01,5 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the LPC2214?
  The maximum clock frequency for the LPC2214 is 60 MHz, but it can be overclocked to 70 MHz with some limitations.
• How do I configure the pin multiplexing on the LPC2214?
  The pin multiplexing on the LPC2214 is configured using the PINSEL registers. Each peripheral function has a corresponding PINSEL register that determines which pins are used for that function.
• What is the maximum amount of current that can be sourced or sunk by the GPIO pins?
  The maximum amount of current that can be sourced or sunk by the GPIO pins on the LPC2214 is 4 mA per pin, with a total current limit of 100 mA for all GPIO pins combined.
• How do I use the ADC on the LPC2214?
  The ADC on the LPC2214 is a 10-bit successive approximation ADC. It can be configured using the ADC registers, and the conversion result can be read from the ADCR register.
• What is the purpose of the bootloader on the LPC2214?
  The bootloader on the LPC2214 is used to load user code into the flash memory of the microcontroller. It can be used to update the firmware of the device in the field.
