15. Fft_rw_err_int

15.1. Function description:

This demo shows how to trigger FFT ICB bus write & read error interrupt.

By setting the address of FFT data output & TF data to 0 to trigger the ICB bus write & read error interrupt:

• Enable global interrupt & register FFT interrupt.

• Initialize & configure the FFT, the input data means is RIRI.

• Enable ICB bus write & read error interrupt.

• Set the address of FFT data output & TF data to 0, and start calculation.

• Waiting trigger the related interrupt and enter interrupt service routine.

Note

The golden data just fit for the RTL cofiguration: FFT Max point is 4096.

15.2. Test result:

If successfully trigger and enter interrupt service routine, then print pass, if not print fail.

15.3. IO connection:
