Chapter 21: LPC43xx/LPC43Sxx General Purpose DMA (GPDMA)
21.6.6 DMA Raw Interrupt Terminal Count Status Register
The RAWINTTCSTAT Register is read-only and indicates which DMA channel is
requesting a transfer complete (terminal count interrupt) prior to masking. (Note: the
IntTCStat Register contains the same information after masking.) A HIGH bit indicates
that the terminal count interrupt request is active prior to masking.
21.6.7 DMA Raw Error Interrupt Status Register
The RAWINTERRSTAT Register is read-only and indicates which DMA channel is
requesting an error interrupt prior to masking. (Note: the IntErrStat Register contains the
same information after masking.) A HIGH bit indicates that the error interrupt request is
active prior to masking.

INTERRCLR
Writing a 1 clears the error interrupt request (IntErrStat)
for DMA channels. Each bit represents one channel:
0 - writing 0 has no effect.
1 - clears the corresponding channel error interrupt.
