1-2 Console Hardware
1.1 Processor Console Hardware
The system processor module has several features dedicated to
support of the console and diagnostic hardware.
The following hardware provides console support:
• 128-Kbyte flash-erasable programmable read-only memories
(FEPROMs) hold the console program, diagnostic software, and boot-
strap routines.
• One 128-Kbyte FEPROM contains code that performs minimal initiali-
zation and testing functions required to bring up the console environ-
ment. It also contains flash ROM recovery code.
• One 8-Kbyte electrically erasable programmable read-only memory
(EEPROM) holds console parameters, bootstrap, and error logging in-
formation.
• One dual universal asynchronous receiver/transmitter (UART) sup-
ports programmable baud rates, parity, stop bits, and character length.
• Logic and registers allow the console to enable or disable halts, cause a
system reset, and provide console communication.
• Hardware provides time-of-year and interval timer functions.
• Several LEDs display status and error information.
