LM3S8933-IQC50-A2 Frequently Asked Questions (FAQs)

• What is the recommended crystal oscillator frequency for the LM3S8933?
  The recommended crystal oscillator frequency for the LM3S8933 is 12 MHz, but it can operate with a frequency range of 10 MHz to 20 MHz.
• How do I configure the USB interface on the LM3S8933?
  The USB interface on the LM3S8933 can be configured using the USB Device Controller (UDC) module. The UDC module provides a USB 2.0 full-speed device interface and supports both device and host modes. The configuration is done through the USB Device Controller Register (UDC_REG) and the USB Endpoint Register (EP_REG).
• 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 on the LM3S8933 is 4 mA. However, it is recommended to limit the current to 2 mA to ensure reliable operation.
• How do I implement a watchdog timer on the LM3S8933?
  The LM3S8933 has a built-in watchdog timer (WDT) module that can be used to reset the device in case of a software fault. The WDT can be enabled and configured using the Watchdog Timer Control Register (WDTCTL) and the Watchdog Timer Load Register (WDTLOAD).
• What is the maximum operating temperature range for the LM3S8933?
  The maximum operating temperature range for the LM3S8933 is -40°C to 85°C. However, the device can be operated at temperatures up to 105°C with reduced performance and reliability.
