stm32 用FSMC控制CPLD的读写 出现了问题

Anthony_brave

现在 配置的是模式A    通过下面代码可以看出EXTMOD为低。所以是通过BTR寄存器来控制读写的。  

FSMC_NORSRAMInitStructure.FSMC_WriteOperation = FSMC_WriteOperation_Enable;
  FSMC_NORSRAMInitStructure.FSMC_WaitSignal = FSMC_WaitSignal_Disable;
  FSMC_NORSRAMInitStructure.FSMC_ExtendedMode = FSMC_ExtendedMode_Disable;
  FSMC_NORSRAMInitStructure.FSMC_WriteBurst = FSMC_WriteBurst_Disable;
  FSMC_NORSRAMInitStructure.FSMC_ReadWriteTimingStruct = &p;
  FSMC_NORSRAMInitStructure.FSMC_WriteTimingStruct = &p;

如下图，怎么控制NWE NOE呢？

事实上，NWE NOE只要配置完就不用控制了。自动读写，

正点原子
