22. PCI Controller (PCIC)
The DMA transfer PCI address register [3:0] (PCIDPA [3:0]) specifies the starting address at the
PCI when performing DMA transfers. This 32-bit read/write register can be accessed from both
the PP bus and PCI bus.
The PCIDPA register is initialized to H'00000000 at a power-on reset and a software reset.
The transfer address of a byte boundary or character boundary can be set, but the 2 least
significant bits of this register are ignored, and the data of the longword boundary is transferred.
Before starting a DMA transfer, be sure to write to this register. After a DMA transfer starts, the
value in the register is not retained. Always re-set the register value before starting a new DMA
transfer after a DMA transfer has been completed.
Bits 31 to 0—DMA Transfer PCI Starting Address (PDPA31 to 0): Set the PCI starting
address for DMA transfer.
