Staging:CC3220 Interrupt Demo Application (Texas Instruments NDA restrictions applicable)

= Application details =

The objective of this application is to showcase interrupt preemption and tail-chaining capabilities. Nested interrupts are synthesized when the interrupts have the same priority, increasing priorities, and decreasing priorities. With increasing priorities, preemption will occur; in the other two cases tail-chaining will occur.

Source Files briefly explained

 * pinmux - Pinmux configurations as required by the application.
 * main - Main file that showcases Interrupt Preemption capabilities
 * uart_if - To display status information over the UART
 * systick_if - Setup the systick values and registers SysTick handler

= Usage =


 * Setup a serial communication application (HyperTerminal/TeraTerm). For detail info visit Terminal setup

On the host PC. The settings are:   - Port: Enumerated COM port (XDS110 Class Application/User UART)    - Baud rate: 115200    - Data: 8 bit    - Parity: None    - Stop: 1 bit    - Flow control: None


 * Run the reference application (Flashing the bin/IAR/CCS).
 * Observe the status messages on the host over serial port to understand the sequence of operations performed by the application.

= Limitations/Known Issues =

None.
