Description
Reserved. Write as 0. Return 0 on read.
Bus Mastering IDE Base Address Enable. This bit should be set to enable access to
the native register set after the base address has been set.
0: Disable (i.e., cannot access native registers in ATAC).
1: Enable (normal operation).
Reserved. Write to 0. Return 0 on read.
Bus Mastering IDE Base Address. These bits form the base address of the ATAC
native register set. Users may write the full address, including bits [2:0], knowing that
bits [2:0] will drop off and be assumed as 000.
Address Range (Read Only). Hard wired to 001. This indicates that the I/O base
address is in units of bytes.
