Signal Descriptions
This chapter describes the signals that comprise the L64381’s bit-level
interface to other devices. This description is intended for hardware
designers who are connecting the product to other components.
This chapter is divided into seven sections:
Section 3.1, “Network Interface Signals”
Section 3.2, “Bus Interface Signals”
Section 3.3, “Processor Interface Signals”
Section 3.4, “Status Signals”
Section 3.5, “Clock Signals”
Section 3.6, “Test Signals”
Section 3.7, “Miscellaneous Signals”
The product’s interface signals are described in alphabetical order by
mnemonic. Each signal definition contains the mnemonic and the full sig-
nal name. The mnemonics for signals that are active LOW are marked
with an overbar; all others are active HIGH. For example, WE is active
LOW, and RD is active HIGH.
In the descriptions that follow, the verb assert means to drive TRUE or
active. The verb deassert means to drive FALSE or inactive.
Figure 3.1 shows the logic diagram for the L64381.
