请问tms320f28377d连接16位异步RAM连接方式？

第一个应该是nor flash   后面一个应该是NAND FLASH
关于最低位地址    最好看看mcu内部总线对齐情况  
是否偏了一位   c5000存在这个问题

如果是接16位的异步存储器，则需要按照你的第一个图来连：EM1BA1 接设备的最低位。
Of special note is the connection between the EMIF and the external device's address bus. The EMIF
address pin EM1A[0] always provides the least significant bit of a 32-bit word address. Therefore, when
interfacing to a 16-bit or 8-bit asynchronous device, the EM1BA[1] and EM1BA[0] pins provide the leastsignificant bits of the halfword or byte address, respectively. Figure 25-9 and Figure 25-10 show the
mapping between the EMIF and the connected device's data and address pins for various programmed
data bus widths. The data bus width may be configured in the asynchronous n configuration register
(ASYNC_CSn_CR).


EM1DQM[x:0] O Active-low byte enables.
When interfacing to SDRAM, these pins are connected to the DQM pins of the SDRAM to
individually enable/disable each of the bytes in a data access.
When interfacing to an asynchronous device, these pins are connected to byte enables. See
Section 25.3.6 for details.
主要是字节访问使能。
