ATA100
17.1. Overview
This document is the functional specification for the ATA Host Interface Controller used in TX4939.
The following table lists the transfer modes that this interface supports.
Rev. 3.1 November 1, 2005
Compliant with ATA/ATAPI-6.
Can interface with the TX49 G-Bus.
Can become the Bus Master and transfer data to external memory.
Data bus widths of 64 bits, can select Byte Big/Little Endian.
Can select incrementing/decrementing/fixed address of the transfer address.
Realizes Auto DMA mode. (When issuing a DMA command, settings such as the transfer direction and transfer
start are unnecessary. After the command is issued, this controller can realize data transfer and only has to wait
for a Transfer End interrupt.)
Sets up the reset timer.
Has 16
transferring to/from the device and when transferring to/from the external memory.
Can issue Timing Error interrupts.
Can Support Scatter Gather DMA.
