System Status Register 2
The MVME6100 board system status register 2 provides board control and
status bits.
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.
