07KT98 H2 GJR5253100R0278通过执行对WDT保持有效寄存器（WKPA）的写入来刷新看门狗定时器。数据书面材料是无关紧要的。WDT保活寄存器（WKPA）启用时，通过写入防止看门狗定时器重置系统至位于中地址偏移量0x0C处的WDT保持有效寄存器（WKPA）BAR2在选定的超时时间内。

写入此位置的数据为：无关的VMIVME-7807/VME-7807RC提供32KB的非易失性RAM。这个记忆从BAR1中的地址开始映射到32K地址空间。此内存为可随时使用，并支持从主机进行字节、短字和长字访问PCI总线。当板的电源断开时，此内存的内容将保留远离的。VMIVME-7807/VME-7807RC具有可选的板载CompactFlash质量容量高达2GB的存储系统。

此CompactFlash磁盘显示在用户作为智能ATA（IDE）磁盘驱动器，具有相同的功能和作为“旋转介质”IDE硬盘的功能。VMIVME-7807/VME-7807RCBIOS包括一个选项，允许板从CompactFlash启动，使用用户提供的操作系统。

07KT98 H2 GJR5253100R0278 Refreshes the watchdog timer by performing a write to the WDT keep-alive register (WKPA). Data written material is irrelevant. When the WDT Keepalive register (WKPA) is enabled, reset the system by writing the Guard Dog timer to the WDT Keepalive register (WKPA) BAR2 at the middle address offset 0x0C within the selected timeout period.

The data written to this location is: the unrelated VMIVME-7807/VME-7807RC provides 32KB of non-volatile RAM. This memory is mapped from the address in BAR1 to the 32K address space. This memory is readily available and supports byte, short, and long word access to the PCI bus from the host. When the board's power supply is disconnected, the contents of this memory will remain away. The VMIVME-7807/VME-7807RC has optional on-board CompactFlash quality storage systems with capacities up to 2GB.

This CompactFlash disk is displayed to the user as a Smart ATA (IDE) disk drive, with the same functionality as a "spinning media" IDE hard disk. The VMIVME-7807/VME-7807RCBIOS includes an option to allow the board to boot from CompactFlash, using a user-provided operating system.
