This register defines the PRD Table Address register for IDE Channel #1 in the SiI3512 controller. The register bits are
also mapped to PCI Configuration Space, Offset 0x7C and Base Address 5, Offset 0x0C. See PRD Table Address – IDE1
section on page 53 for bit definitions.
Internal Register Space – Base Address 5
These registers are 32 bits wide and define the internal operation of the SiI3512 controller. The access types are defined
as follows: R=read, W=write, and C=clearable by some write operation. Access to this register is through the PCI
Memory space. The Base Address 5 can be disabled by setting input BA5_EN to low.
