stm32f103 FSMC同步模式配置FPGA

zcx319

FSMC在同步模式下，FSMC_CLK怎么没输出啊？

 配置是 

 FSMC_NORSRAMInitStructure.FSMC_Bank = FSMC_Bank1_NORSRAM1;                 
 FSMC_NORSRAMInitStructure.FSMC_DataAddressMux = FSMC_DataAddressMux_Disable;
 FSMC_NORSRAMInitStructure.FSMC_MemoryType = FSMC_MemoryType_PSRAM;           
 FSMC_NORSRAMInitStructure.FSMC_MemoryDataWidth = FSMC_MemoryDataWidth_16b;  
 FSMC_NORSRAMInitStructure.FSMC_BurstAccessMode = FSMC_BurstAccessMode_Enable; 
 FSMC_NORSRAMInitStructure.FSMC_AsynchronousWait = FSMC_AsynchronousWait_Disable;   
 FSMC_NORSRAMInitStructure.FSMC_WaitSignalPolarity = FSMC_WaitSignalPolarity_Low;     
 FSMC_NORSRAMInitStructure.FSMC_WrapMode = FSMC_WrapMode_Disable;   
 FSMC_NORSRAMInitStructure.FSMC_WaitSignalActive = FSMC_WaitSignalActive_BeforeWaitState;
 FSMC_NORSRAMInitStructure.FSMC_WriteOperation = FSMC_WriteOperation_Enable;      
 FSMC_NORSRAMInitStructure.FSMC_WaitSignal = FSMC_WaitSignal_Enable;  
 FSMC_NORSRAMInitStructure.FSMC_ExtendedMode = FSMC_ExtendedMode_Disable; 
 FSMC_NORSRAMInitStructure.FSMC_WriteBurst = FSMC_WriteBurst_Enable;       
 FSMC_NORSRAMInitStructure.FSMC_ReadWriteTimingStruct = &p;               
 FSMC_NORSRAMInitStructure.FSMC_WriteTimingStruct = &p;                  

 FSMC_NORSRAMInit(&FSMC_NORSRAMInitStructure);
 FSMC_NORSRAMCmd(FSMC_Bank1_NORSRAM1, ENABLE);//使能BANK1，SRAM1

FSMC_CLK是不是配置好就可以输出了？还是需要怎么样啊

正点原子
