Word 64: Advanced PIO Data Transfer Mode
Bits [7:0] is defined as the PIO data and register transfer supported field. If this field is supported,
bit 1 of word 53 shall be set to one. This field is bit significant. Any number of bits may be set to
one in this field by the device to indicate the PIO modes the device is capable of supporting. Of
these bits, bits [7:2] are Reserved for future PIO modes.

Word 65: Minimum Multi-word DMA Transfer Cycle Time Per Word
This field defines the minimum Multi-word DMA transfer cycle time per word. This field defines, in
nanoseconds, the minimum cycle time that the NANDrive supports when performing Multi-word
DMA transfers on a per word basis. NANDrive supports up to Multi-word DMA Mode-2, so this field
is set to 120ns.
Note: NANDrive is capable of supporting Multi-word DMA Mode-4 cycle time of 80ns (0050H).
Word 66: Device Recommended Multi-word DMA Cycle Time
This field defines the NANDrive recommended Multi-word DMA transfer cycle time. This field
defines, in nanoseconds, the minimum cycle time per word during a single sector host transfer
while performing a multiple sector READ DMA or WRITE DMA command for any location on the
media under nominal conditions. If a host runs at a faster cycle rate by operating at a cycle time of
less than this value, the NANDrive may negate DMARQ for flow control. The rate at which
DMARQ is negated could result in reduced throughput despite the faster cycle rate. Transfer at
this rate does not ensure that flow control will not be used, but implies that higher performance
may result. NANDrive supports Multi-word DMA Mode-2, so this field is set to 120ns.
Note: NANDrive is capable of supporting Multi-word DMA Mode-4 cycle time of 80ns (0050H).
