| Message: | atusb/fw/: aggregate interrupts while waiting - board_app.c (INT0_vect): always read IRQ_STATUS, even if an interrupt is already enqueued - board_app.c (INT0_vect): if an interrupt is enqueued, accumulate the interrupts signaled since - board_app.c (irqs_more): when a pending transfer completes, send interrupts accumulated since (if any) |
