Atmel dataflash页面大小？

对于ATMEL数据闪存，例如AT45DB161D，有两种类型的页面大小（每页512或528字节）。
当用作“串行spi配置模式”时，使用IMPACT通过FPGA间接编程SPI时使用哪个值？
上电后从spi闪存配置时要使用的值是多少？
我的fpga是xc3s500e-pq208，ise / edk版本是10.1.3。



以下为原文

For ATMEL dataflash such as AT45DB161D, there are 2 types of page size( 512 or 528 bytes per page).

When used as "serial spi configuration mode", which value used when indirectly programing SPI with IMPACT though fpga?
And which value to be used when configuration from spi flash after power up?

My fpga is xc3s500e-pq208, and ise/edk version is 10.1.3.
