LM4F232H5QCFIG Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the LM4F232H5QCFIQ?
  The maximum operating frequency of the LM4F232H5QCFIQ is 80 MHz, but it can be overclocked to 100 MHz with some limitations.
• How do I configure the clock source for the LM4F232H5QCFIQ?
  The clock source can be configured using the SYSCTL_RCC register. You can choose between the internal oscillator, external crystal oscillator, or an external clock source.
• 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 is 8 mA, but it's recommended to limit it to 4 mA to ensure reliable operation.
• How do I use the analog-to-digital converter (ADC) on the LM4F232H5QCFIQ?
  The ADC can be configured using the ADCCTL0 and ADCCTL1 registers. You need to select the ADC clock source, set the conversion mode, and configure the ADC pins.
• What is the purpose of the brown-out reset (BOR) feature on the LM4F232H5QCFIQ?
  The BOR feature detects when the voltage supply drops below a certain threshold and resets the microcontroller to prevent unexpected behavior or data corruption.
