请问有什么办法能在串行模式下配置XCF16P?

请帮我找一个在串行模式下配置XCF16P以配置Spartan6 LX45T的方法。
除了以下消息之外,我无法在XCF16P的数据表上找到方法:
在ISPEN期间(未钳位时)和选择串行模式进行配置时,D1-D7输出设置为高阻态。
当PROM用于串行模式时,D1-D7引脚可以保持不连接状态。
但是我可以在哪里设置ISPEN?
非常感谢你的回答。
周末愉快。

以下为原文

Please help me to find a way to setup XCF16P in serial mode to configure Spartan6 LX45T.

I can't find a way on the datasheet of XCF16P except the follow message:

The D1-D7 outputs are set to a high-impedance state during
ISPEN (when not clamped) and when serial mode is selected
for configuration. The D1-D7 pins can be left unconnected
when the PROM is used in serial mode.

But where I can set up ISPEN?

Many thanks for your answer.

Have a nice weekend.

我相信在这种情况下,“ISPEN”正在谈论系统内的JTAG状态逻辑状态
节目。
您可以在Impact中选择串行与并行模式
为这些部分生成PROM文件。
这是现有的电路板,还是您正在制作新设计?
因为通常我会建议
节省一些资金并使用标准SPI闪存来配置Spartan-6部件。
你可以编程
他们使用S6的JTAG(间接SPI闪存编程),它们可以使用
由设计运行后(对MicroBlaze系统以及其他用途有用)。

以下为原文

I believe that in this context "ISPEN" is talking about a state of the JTAG state logic during in-system
programming.  The selection of serial vs. parallel mode should be available in Impact when you
generate the PROM file for these parts.
 
Is this for an existing board, or are you making a new design?  Because normally I would suggest
saving some money and using a standard SPI flash to configure Spartan-6 parts.  You can program
them using the JTAG of the S6 (indirect SPI flash programming) and they are available for use
by the design after it is running (useful for MicroBlaze systems as well as other purposes).

是的,我正在制作新的设计。
参考Spartan6工具包使用不同的配置方式让我感到困惑。
我现在将使用XCF16P来降低风险。
如果有可能,您能告诉我正常SPL闪存的部件号吗?
非常感谢。

以下为原文

Yes, I am making the new design.
 
The reference Spartan6 kit used the differenct way to configure that makes me confused.
 
I will use XCF16P for now to reduce the risk.
 
If it is possible, would you let me know the part number of normal SPL flash?
 
Many thanks.
