The DMA transfer local bus start address register [3:0] (PCIDLA [3:0]) specifies the starting
address at the local bus when performing DMA transfers.
This 32-bit read/write register can be accessed from both the PP bus and PCI bus.
The PCIDLA register is initialized to H'00000000 at a power-on reset and a software reset.
