I/O Memory Of Intelligent Dma - Epson S1C33210 Technical Manual

V DMA BLOCK: IDMA (Intelligent DMA)
Trap vector
The trap vector address for an interrupt upon completion of IDMA transfer by default is set to 0x0C00068.
The trap table base address can be changed using the TTBR registers (0x48134 to 0x48137).
