I’m working in double buffer mode. I’ve noted that, in case of a good reception event, the high-to-low transition of the IRQ line is spurious and my host gets a second rising-edge IRQ event. I’ve further seen the spike with the oscilloscope. The spurious falling edge occurs while the host program is clearing SYS_STATUS_ALL_RX_GOOD flags in the dwt_isr callback. This seems not to appear in single-buffer reception mode. My IRQ line is pulled-down and I do rx re-enable manually. Is this behavior correct or is my module misconfigured?
