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).
