general purpose Clock and Control pins. The LIU interface consists of 12 pins.
The Microprocessor interface consists of six clock and control inputs, an 8-bit
data bus, and an 11-bit address bus. There are six JTAG/Scan pins and eight
status pins. The SI-Bus interface consists of 48 transmit pins and 56 receive pins.
There are 95 power and 33 ground pins. Pin descriptions are given in
NOTE:
An asterisk (*) following a pin label indicates that the pin logic level is
active low.
