Part Number: TMS320F28375S I'm going to use TMS320F28375S. I want to connect two 16bit SDRAMs using EMIF1 configured as 32 bit bus. In the TRM(SPRUHX5F), Table 25-14 (p.2424) does not mention EM1DQM[2] and EM1DQM[3] which should be connected to one of the SDRAM. It seems that EM1DQM[2] and EM1DQM[3] are driven during WRT command. Which logical address bit drives EM1DQM[2] and EM1DQM[3]? Best Regards, Satoshi Shinohara
