Word 163: CF 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.
Notice! The use of True IDE PIO Modes 5 and above or of Multiword DMA Modes 3 and above
impose significant restrictions on the implementation of the host:
Additional Requirements for CF Advanced Timing Modes.
There are four separate fields defined that describe support and selection of Advanced PIO timing modes
and Advanced Multiword DMA timing modes. The older modes are reported in words 63 and 64.
Word 63: Multiword DMA transfer and 6.2.1.6.19: Word 64: Advanced PIO transfer modes supported.
Bits 2-0: Advanced True IDE PIO Mode Support Indicates the maximum True IDE PIO mode supported by
the card.
Value Maximum PIO mode timing selected
0 Specified in word 64
1 PIO Mode 5
2 PIO Mode 6
3-7 Reserved
Bits 5-3: Advanced True IDE Multiword DMA Mode Support Indicates the maximum True IDE Multiword
DMA mode supported by the card.
Value Maximum Multiword DMA timing mode supported
0 Specified in word 63
1 Multiword DMA Mode 3
2 Multiword DMA Mode 4
3-7 Reserved
Bits 8-6: Advanced True IDE PIO Mode Selected Indicates the current True IDE PIO mode selected on the
card.
Value Current PIO timing mode selected
0 Specified in word 64
1 PIO Mode 5
2 PIO Mode 6
3-7 Reserved
Bits 11-9: Advanced True IDE Multiword DMA Mode Selected Indicates the current True IDE Multiword
DMA Mode Selected on the card.
Value Current Multiword DMA timing mode selected
0 Specified in word 63
1 Multiword DMA Mode 3
2 Multiword DMA Mode 4
3-7 Reserved
Bits 15-12 are reserved.
Word 164: CF 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.
Notice! The use of PCMCIA I/O or Memory modes that are 100ns or faster impose significant
restrictions on the implementation of the host:
Additional Requirements for CF Advanced Timing Modes.
