BD_FAIL

Board Fail. This bit is used to control the Board Fail LED located on the front panel. A set condition illuminates the front panel LED and a cleared condition extinguishes the front panel LED.

EEPROM_WP

Not used on the MVME6100.

FLASHA_WP

Software Flash Bank A Write Protect. This bit is to provide software- controlled protection against inadvertent writes to the expansion FLASH memory devices. Clearing this bit and disabling the HW write-protect will enable writes to the Bank A Flash devices. This bit is set during reset and must be reset by the system software to enable writing of the flash devices.
