Bits 31:6 Reserved, must be kept at reset value
Bit 5 CEIF: Configuration error interrupt flag
This bit is set when the START bit of DMA2D_CR, DMA2DFGPFCCR or
DMA2D_BGPFCCR is set and a wrong configuration has been programmed.
Bit 4 CTCIF: CLUT transfer complete interrupt flag
This bit is set when the CLUT copy from a system memory area to the internal DMA2D
memory is complete.
Bit 3 CAEIF: CLUT access error interrupt flag
This bit is set when the CPU accesses the CLUT while the CLUT is being automatically
copied from a system memory to the internal DMA2D.
Bit 2 TWIF: Transfer watermark interrupt flag
This bit is set when the last pixel of the watermarked line has been transferred.
Bit 1 TCIF: Transfer complete interrupt flag
This bit is set when a DMA2D transfer operation is complete (data transfer only).
Bit 0 TEIF: Transfer error interrupt flag
This bit is set when an error occurs during a DMA transfer (data transfer or automatic
CLUT loading).
