I'm stepping through some code that keeps getting stuck in DefaultISR.
At first the USB0_IRQHandler (or lack thereof) was causing this, since putting in a blank handler, now it's UART1_IRQHandler.
Neither of these interrupts should be enabled, so I'd like to be able to read the current NVIC register setup in debug and so I can see exactly which interrupts have been enabled and which have not. Then I will hopefully be able to track down where the interrupts are going iffy.
Incase it matters, I'm currently using a KL25Z128 chip (FRDM K25 board)
