Data Sheet
3.0 PIN ASSIGNMENTS
The signal/pin assignments are listed in Table 3-1. Low
active signals have a “#” suffix. Pin types are Input, Output,
or Input/Output. Signals whose source is the host are des-
ignated as inputs while signals that the ATA Flash Disk
Controller sources are outputs.
The ATA Flash Disk Controller functions in ATA mode,
which is compatible with IDE hard disk drives.
