3.5 ENHANCED PORT PROCESSOR SIGNAL DESCRIPTIONS  
This section describes the Enhanced Port Processor signals.  
The following notation is used to describe the signal type:  
I
Input pin  
O
B
Output pin  
Bidirectional Input/Output pin  
The signal description also includes the type of buffer used for the particular signal:  
PECL  
STI  
PECL are Pseudo-ECL (positive voltage ECL) compatible signals.  
STI is a very high-speed asynchronous communications protocol used to connect devices  
that may be 1 to 15 meters apart.  
HSTL  
All HSTL specifications are consistent with EIA/JEDEC Standard, EIA/JESD8-6 High  
Speed Transceivers Logic (HSTL): A 1.5V Output Buffer Supply Voltage based Interface  
Standard for Digital Integrated Circuits”, dated 8/95. Refer to these specifications for more  
information.  
CMOS  
The CMOS Buffers are either 3.3 V compatible or 2.5 V Low Voltage TTL compatible  
signals, as noted.
