SB82371SB Product Details


This section contains a detailed description of each signal. The signals are arranged in functional groups according to their interface. Note that the ’#’ symbol at the end of a signal name indicates that the active, or asserted state occurs when the signal is at a low voltage level. When ’#’ is not present after the signal name, the signal is asserted when at the high voltage level. The terms assertion and negation are used extensively. This is done to avoid confusion when working with a mixture of ’active-low’ and ’active-high’ signals. 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. Note that certain signal pins provide two separate functions. At the system level, these pins drive other signals with different functions through external buffers or transceivers. These pins have two different signal names depending on the function. These signal names have been noted in the signal description tables, with the signal whose function is being described in bold font. (For example, LA23/CS1S is in the section describing CS1S and LA23/CS1S is in the section describing LA23).
