7.7. Error Handling in AHB UART

Try these first

1. 1.

   What is an overrun error in UART?

   Hint

   Think about what happens when too much information comes in at once.

2. 2.

   Define a parity error.

   Hint

   Consider how we check data correctness.

3. 3.

   What occurs during an overrun error?

   • New data is stored
   • Old data is overwritten
   • CPU is unaware

   Hint

   Focus on the FIFO behavior when new data arrives.

4. 4.

   Framing errors occur when:

   • True
   • False

   Hint

   Think of the integrity of the data format.

5. 5.

   Design an error handling mechanism for a UART communication application. Include handling strategies for overrun, framing, and parity errors.

   Hint

   Break down the handling mechanisms into manageable functions.

6. 6.

   Analyze the effect of not addressing overrun errors in a real-time system. What could be the long-term impacts?

   Hint

   Consider implications on system reliability and performance.
