STM32的FSMC总线有点疑问。。。。急啊

大家好，我设置了fsmc控制LCD，
请问STM32的fsmc设置完之后，我要给LCD写数据
是不是他会自动的产生LCD的控制信号时序？？？
还有这些时序是从固定的管脚发出的吗？？
这些时序我能不能修改其中的一个管脚的时序？？？


以下是FSMC的初始化代码。
void LCD_FSMCConfig(void)
{
  FSMC_NORSRAMInitTypeDef  FSMC_NORSRAMInitStructure;
  FSMC_NORSRAMTimingInitTypeDef  p;
/*-- FSMC Configuration ------------------------------------------------------*/
/*----------------------- SRAM Bank 4 ----------------------------------------*/
  /* FSMC_Bank1_NORSRAM4 configuration */
  p.FSMC_AddressSetupTime = 1;
  p.FSMC_AddressHoldTime = 0;
  p.FSMC_DataSetupTime = 2;
  p.FSMC_BusTurnAroundDuration = 0;
  p.FSMC_CLKDivision = 0;
  p.FSMC_DataLatency = 0;
  p.FSMC_AccessMode = FSMC_AccessMode_A;
