我使用的MCU为STM32F103VC，在使用FSMC访问外部的SRAM的时候，功能脚上没有输出信号？
在使用中为数据线和地址线复用的形式,所以外部加锁存器进行地址锁存,用NADV信号来控制锁存器的lock脚。
信号连接:
    NADV----&gtB7
    NOE-----&gtD4
    NWE-----&gtD5
    NE1-----&gtD7
    NBL0----&gtE0
    NBL1----&gtE1
我使用的为IAR5.0,使用STM32的库函数
Bit 1 MUXEN: Address/data multiplexing enable bit.
   When this bit is set, the address and data values are multiplexed on the databus, valid only with NOR Flash memory:
   0: Address/Data nonmultiplexed
   1: Address/Data multiplexed on databus (default after reset)

在复用模式下的时候，MemoryType设置为NOR Flash。

我的初始化如下:
/* DMA1 and DMA2, FSMCclock enable */
    RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1 | RCC_AHBPeriph_DMA2|RCC_AHBPeriph_SRAM|RCC_AHBPeriph_FSMC, ENABLE);

void FSMC_SRAM_Init(void)
{
  FSMC_NORSRAMInitTypeDef  FSMC_NORSRAMInitStructure;
  FSMC_NORSRAMTimingInitTypeDef  p;
  GPIO_InitTypeDef GPIO_InitStructure;
  
// RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOD | RCC_APB2Periph_GPIOE , ENABLE);
  
/*-- GPIO Configuration ------------------------------------------------------*/
  /* Set PD.00(D2), PD.01(D3), PD.08(D13), PD.09(D14),
     PD.10(D15),PD.11(A16), PD.14(D0), PD.15(D1) as alternate
     function push pull */
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0 | GPIO_Pin_1 | GPIO_Pin_8 | GPIO_Pin_9 |
                         GPIO_Pin_10 |GPIO_Pin_11 | GPIO_Pin_14 | GPIO_Pin_15;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
  GPIO_Init(GPIOD, &GPIO_InitStructure);
  
  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_7 | GPIO_Pin_8 | GPIO_Pin_9 | GPIO_Pin_10 |
                                GPIO_Pin_11 | GPIO_Pin_12 | GPIO_Pin_13 | GPIO_Pin_14 |GPIO_Pin_15;
  GPIO_Init(GPIOE, &GPIO_InitStructure);
   
  /* PD.04(NOE), PD.05(NWE), PD.07(NE1) configuration */  
  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_4 |GPIO_Pin_5|GPIO_Pin_7;
  GPIO_Init(GPIOD, &GPIO_InitStructure);
  
  /* NBL0, NBL1 configuration */
  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0 | GPIO_Pin_1;
  GPIO_Init(GPIOE, &GPIO_InitStructure);

  /*NADV configuration */
  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_7;
  GPIO_Init(GPIOB, &GPIO_InitStructure);
  
/*-- FSMC Configuration ------------------------------------------------------*/
  p.FSMC_AddressSetupTime = 2;
  p.FSMC_AddressHoldTime = 2;
  p.FSMC_DataSetupTime = 3;
  p.FSMC_BusTurnAroundDuration = 2;
  p.FSMC_CLKDivision = 2;
  p.FSMC_DataLatency = 3;
  p.FSMC_AccessMode = FSMC_AccessMode_B;

  FSMC_NORSRAMInitStructure.FSMC_Bank = FSMC_Bank1_NORSRAM1;
  
  FSMC_NORSRAMInitStructure.FSMC_DataAddressMux = FSMC_DataAddressMux_Enable;
  FSMC_NORSRAMInitStructure.FSMC_MemoryType = FSMC_MemoryType_NOR;
  FSMC_NORSRAMInitStructure.FSMC_MemoryDataWidth = FSMC_MemoryDataWidth_16b;
  FSMC_NORSRAMInitStructure.FSMC_BurstAccessMode = FSMC_BurstAccessMode_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_Disable;
  FSMC_NORSRAMInitStructure.FSMC_ExtendedMode = FSMC_ExtendedMode_Disable;
  FSMC_NORSRAMInitStructure.FSMC_AsyncWait = FSMC_AsyncWait_Disable;
  FSMC_NORSRAMInitStructure.FSMC_WriteBurst = FSMC_WriteBurst_Disable;
  
  FSMC_NORSRAMInitStructure.FSMC_ReadWriteTimingStruct = &p;
  FSMC_NORSRAMInitStructure.FSMC_WriteTimingStruct = &p;

  FSMC_NORSRAMInit(&FSMC_NORSRAMInitStructure);

  /* Enable FSMC Bank1_SRAM Bank */
  FSMC_NORSRAMCmd(FSMC_Bank1_NORSRAM1, ENABLE);  
}
然后我调用FSMC_SRAM_WriteBuffer（），进行写操作。在FSMC章节中，对复用形式下，采用了模式B。

疑问：
1、在使用中定义IO口为AF，但是手册中D0，D1为默认值，也需要定义为AF吗？
2、我的初始化是否出了问题，我现在用示波器观察IO口发现没有波形输出？
