在正常操作期間，一次WDT 超時溢出將產(chǎn)生一次器件復位。如果器件處于休眠狀態(tài)，一次WDT超時溢出將喚醒器件，使其繼續(xù)正常操作（即稱作WDT 喚醒）。對WDTE 設置位清零可以永久性地關閉WDT。后分頻器分配完全是由軟件控制，即它可在程序執(zhí)行期間隨時更改。在例26-1 中，如果需要的預分頻值不是1:1，就不需要對OPTION_REG 寄存器做初始修改。如果需要的預分頻值是1:1，那么先向OPTION_REG 設置一個非1:1 的臨時預分頻值，在完成其它操作后，在最后修改OPTION_REG 時再設置1:1 的預分頻值。這樣操作，主要是因為無法知道TMR0 預分頻器的當前計數(shù)值，而且分頻器更改后，該值將變?yōu)閃DT 后分頻器的當前計數(shù)值，所以必須遵循示例中的代碼順序。如果沒有按照示例中的代碼順序改變OPTION_REG 寄存器，那么無法準確得知WDT 復位前的時間。

The Virtex™-4 user access register (USR_ACCESS_VIRTEX4) is a 32-bit register thatprovides direct access to bitstream data by the FPGA fabric. It is useful for loadingPowerPC™ 405 (PPC405) processor caches and/or other data into the FPGA after the FPGAhas been configured, thus achieving partial reconfiguration. The USR_ACCESS_VIRTEX4register is programmed through the bitstream with a command that writes a series of 32-bitwords.

給出了電路的結構組成,根據(jù)KAI-02150的驅動和輸出參數(shù)要求設計了各個模塊的具體電路。通過SPI接口對AD9920A的寄存器進行配置,可以滿足多種工作模式切換的需要。與傳統(tǒng)的CCD模擬前端采集方案相比,文中的設計更加靈活簡單、穩(wěn)定可靠。測試表明,設計的輸出驅動時鐘滿足KAI-02150的輸入要求,可以驅動CCD輸出模擬信號,并完成相關雙采樣和A/D轉換得到數(shù)字視頻信號。
