Hi Naveen Kumar, [quote userid="640255" url="~/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1498716/tms570lc4357-ep-multi-buffered-serial-peripheral-interface-module-mibspi-with-parallel-pin-option"] The datasheet states that MIBSPI5 has 4 MOSI and 4 MISO lines, but the reference manual states that MIBSPI5 has 2 MOSI and 2 MISO lines. The MCU has dedicated 4 MOSI and 4 MISO pins. Can I use the MIBSPI5 module with 4 MOSI and 4 MISO lines in my design? [/quote] The datasheet information is correct. Yes, MibSPI5 has 4MOSI and 4MISO lines. You can refer below page in the datasheet here they mentioned pin numbers for all the pins. As you can see here there pins for four MOSI and 4 MISO in MibSPI5 (highlighted in yellow). So, this MIBSPI5 instance will support 4-wire parallel communication. -- Thanks & regards, Jagadish.
