RTOS Timer tick handler is now the same as any other ISR. This causes a few subtle behaviour changes that seem OK but are worth noting: * RTOS tick handler sdk__xt_timer_int() is now called from one stack frame deeper (inside _xt_isr_handler()), whereas before it was called from the level above in UserHandleInterrupt. I can't see any way that the extra ~40 bytes of stack use here hurt, though. * sdk__xt_timer_int() was previous called after all other interrupts flagged in the handler, now it's called before the TIMER FRC1 & FRC2 handlers. The tick handler doesn't appear to do anything particularly timing intensive, though. * GPIO interrupt (value 3) is now lower priority than the SPI interrupt (value 2), whereas before it would have been called before SPI if both interrupts triggered at once. |
