Word 163: Advanced True IDE Timing mode capabilities and settings

This word describes the capabilities and current settings for CFA defined Advanced Timing

modes using the True IDE interface.

There are four sub-fields that describe the Advanced PIO and Advanced Multi-Word DMA

Timing modes supported and selected:

●

Bits 2-0: Advanced True IDE PIO Mode supported.

The returned value is ‘2h’ to indicate that PIO mode 6 is the highest PIO mode

supported.

●

Bits 5-3: Advanced True IDE Multi-Word DMA mode supported.

The returned value is ‘2h’ to indicate that Multi-Word DMA mode 4 is the highest Multi-

Word DMA mode supported.

●

Bits 8-6: Advanced True IDE PIO mode selected.

These bits indicate the current True IDE PIO mode selected on the Card.

●

Bits 11-9: Advanced True IDE Multi-Word DMA mode selected.

These bits indicate the current True IDE Multi-Word DMA mode selected on the Card.

Word 164: Advanced PCMCIA I/O and Memory Timing modes

capabilities and settings

This Word describes the capabilities and current settings for CFA defined Advanced Timing

modes using the Memory and PCMCIA I/O interface:

●

Bits 2-0: maximum Advanced PCMCIA I/O mode supported.

The returned value is ‘3h’ to indicate that 80ns is the maximum I/O timing mode

supported by the Card.

●

Bits 5-3: maximum PCMCIA Memory timing mode supported.

The returned value is ‘3h’ to indicate that 80ns is the maximum PCMCIA Memory

timing mode supported by the Card.
