B&R 7DI140.70 Flash Memory -VMIVME-7697 offers: Optional 8 to 192 MB of flash memory available via secondary IDE port. The VMIVME-7697 BIOS includes the option to allow the board to boot from flash memory. 32-bit timers - The VMIVME-7697 offers users with three 16/32-bit timers (82C54) that are shareable in the PCI memory space and are fully software programmable.

Watchdog Timer -VMIVME-7697 provides software programmable watchdog timer. The watchdog timer is enabled under software control. Once the become watchdog timer is enabled, the on-board software must access the timer otherwise a timeout will occur.

A. Reset the user jumper due to timeout. Independent For jumpers, the software watchdog times out, causing a non-maskable interrupt (NMI) or VMEbus system failure. Battery supported SRAM- The VMIVME-7697 offers 128 KB battery supported SRAM. SRAM is accessible in PCI memory space. When the +5 V power supply is interrupted or disconnected, these voltages remain constant from the unit.

B&R 7DI140.70闪存-VMIVME-7697提供：可选8到192 MB的闪存，可通过辅助IDE端口。VMIVME-7697 BIOS包括：允许板从闪存引导的选项。32位定时器-VMIVME-7697提供具有三个16/32位定时器（82C54）的用户可共用的这些定时器被映射在PCI存储器空间中，并且是完全软件可编程的。

看门狗定时器-VMIVME-7697提供软件可编程看门狗定时器。看门狗定时器在软件控制下启用。一旦成为看门狗定时器已启用，车载软件必须访问定时器否则将发生超时。

A.用户跳线允许超时导致重置。独立的对于跳线，软件看门狗超时导致不可屏蔽中断（NMI）或VMEbus系统故障。电池支持的SRAM-VMIVME-7697提供128 KB电池支持的SRAM。SRAM是可在PCI内存空间中访问。SRAM的内容当+5 V电源中断或断开时，这些电压保持不变从该单元。
