HWA hangs when using back to back FFT3X paramsets

Revision(s) Affected

AWR2944P, AWR2E44P

Details

If FFT3X is enabled in back to back paramsets or as first and last paramsets of a loop, the HWA state machine hangs after the 1st FFT3X paramset is executed without raising any param done interrupt.

Workaround

Use any paramset with FFT3X disabled before using a paramset with FFT3X enabled (users may also go for a No Operation paramset with ACCEL_MODE = 0b111)
