DATASHEET
Chapter 5 Pin Descriptions
This section provides a detailed description of each signal. The signals are arranged in functional
groups according to their associated interface.
The “n” symbol in the signal name indicates that the active, or asserted state occurs when the signal
is at a low voltage level. When “n” is not present before the signal name, the signal is asserted when
at the high voltage level.
The terms assertion and negation are used exclusively. This is done to avoid confusion when working
with a mixture of “active low” and “active high” signal. The term assert, or assertion indicates that a
signal is active, independent of whether that level is represented by a high or low voltage. The term
negate, or negation indicates that a signal is inactive.

CF Data 15-8:
The bi-directional data signals CF_D15-CF_D8 in True IDE
mode data transfer.
In the True IDE Mode, all of task file register operation occur on
the CF_D[7:0], while the data transfer is on CF_D[15:0].
The bi-directional data signal has an internal weak pull-down
resistor.
