Preliminary
2.4: INTST Interrupt Source
This register indicates the source(s) of the interrupt(s) pending. It can also be used as a status register when
the bits are enabled. See Note on Set/Clear Type Registers on page 93 for more details on addressing. Note
that bits in this register always reflect the state of the source register bit: Writing a value will have no effect.
Reserved bits will not take on the written value. The delay of running through a latch has been removed. For
the delayed interrupts feature, writing this register at the end of an interrupt handling routine will guarantee
that interrupt1 and interrupt2 (if enabled) will pulse off, allowing the logic to get ready for the next interrupt
DMA.
