F28377s在做emif异步通讯的时候，整个片选区域都有数据在变，请问这是什么原因？是emif配置的问题吗？

这是EMIF配置，希望大神帮帮忙。谢谢啦。

void EMIF_Init(void)
{
 EALLOW;
 ClkCfgRegs.PERCLKDIVSEL.bit.EMIF1CLKDIV = 0x1;
 EDIS;

 EALLOW;
 //Disable Access Protection (CPU_FETCH/CPU_WR/DMA_WR)
 Emif1ConfigRegs.EMIF1ACCPROT0.all = 0x1;  // DMA写保护允许     EMIF1MSEL:找不到寄存器配置说明
 // Commit the configuration related to protection. Till this bit remains set
 // content of EMIF1ACCPROT0 register can't be changed.
 Emif1ConfigRegs.EMIF1COMMIT.all = 0x1;
 // Lock the configuration so that EMIF1COMMIT register can't be
 // changed any more.
 Emif1ConfigRegs.EMIF1LOCK.all = 0x1;   // 锁定写入保护
 EDIS;

 Emif1Regs.ASYNC_CS2_CR.bit.ASIZE   =1;  // 16Bit Memory Interface
 Emif1Regs.ASYNC_CS2_CR.bit.R_HOLD  =14;  // Read Hold time of 1 Emif Clock
 Emif1Regs.ASYNC_CS2_CR.bit.R_SETUP =6;  // Read Strobe time of 4 Emif Clock
 Emif1Regs.ASYNC_CS2_CR.bit.R_STROBE=6;  // Read Setup time of 1 Emif Clock
 Emif1Regs.ASYNC_CS2_CR.bit.W_HOLD  =14;  // Write Hold time of 1 Emif Clock
 Emif1Regs.ASYNC_CS2_CR.bit.W_SETUP =6;  // Write Strobe time of 1 Emif Clock
 Emif1Regs.ASYNC_CS2_CR.bit.W_STROBE=6;  // Write Setup time of 1 Emif Clock
 Emif1Regs.ASYNC_CS2_CR.bit.TA =8;   // Turn Around time of 2 Emif Clock
 Emif1Regs.ASYNC_CS2_CR.bit.SS =1;   // EMIF_ASYNC_SS_EnABLE
 Emif1Regs.ASYNC_CS2_CR.bit.EW =1;   // Extended Wait Enable.

 Emif1Regs.INT_MSK_SET.bit.AT_MASK_SET = 1;
 setup_emif1_pinmux_async_16bit(0);
}

您好，就是我使用F28377S与FPGA进行EMIF通讯。然后片选EM1CS2区域。

如下为CMD配置： ZONE2A    : origin = 0x110000, length = 0x000020     /*读取与ram的中FPGA所放数的地址*/
                               ZONE2B    : origin = 0x110120, length = 0x0000E0     /*写FPGA_RAM的地址*/
                               ZONE2D      : origin = 0x200000, length = 0x020000

                              RD_FPGA  : > ZONE2A,     PAGE = 1
                              WR_FPGA   : > ZONE2B,     PAGE = 1

主函数定义：

                               #pragma DATA_SECTION(RD_FPGA1,"RD_FPGA");
                               #pragma DATA_SECTION(WR_FPGA1,"WR_FPGA");

我理解的是这样配置的话，读的数据只会出现在  0x110000, length = 0x000020  区域，写的数据只会出现在  origin = 0x110120, length = 0x0000E0区域。但是现在debug模式下查看，整个EMIF数据区 0x0010 0000~0x003D FFFF都有数据显示。不知道为什么？
