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.
