IDE Start Address Register [0xC04A] [R/W]
Table 85. IDE Start Address Register
Register Description
The IDE Start Address register holds the start address for an IDE
block transfer. This register is byte addressed and IDE block
transfers are 16-bit words, therefore the LSB of the start address
is ignored. Block transfers begin at IDE Start Address and end
with the final word at IDE Stop Address. When IDE Start Address
equals IDE Stop Address, the block transfer moves one word of
data.

...Address
The hardware keeps an internal memory address counter. The
two MSBs of the addresses are not modified by the address
counter. Therefore, the IDE Start Address and IDE Stop Address
must reside within the same 16K byte block.
Address (Bits [15:0])
The Address field sets the start address for an IDE block transfer.
