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.

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.
