大家好:
我看到datasheet关于spi flash启动有这样描述:
26.1.7.6.1 Features
• Supports 12-MHz clock (50% duty cycle).
• Supports only SPI Mode 3 (clock polarity = 1, clock phase = 1).
• Supports only 24-bit addressable EEPROMs.
• Supports only 4-pin SPI mode (CS, CLK, Serial Input, Serial Output).
• The boot devices must be connected to chip select 0 and must support the read command (03h).
• The boot image is copied into internal memory and then executed.
这个说明spi只能接16M的norflash吗?目前我们项目想用32Mnorflash不知是否可行?谢谢!
