Hi,

Can we interface external FLASH with SPI/QSPI with SSI compatible pins given in MSP432E401Y micro controller.

Refer Table 4.3, from page 27 of datasheet.

As SSI and SPI signals differs from each other as given in below table.

Kindly clarify!

Hi Aravind,

The QSSI module supports Freescale SPI and TI Synchronous serial frame format (TI's version of SPI), we actually have an example code interfacing with external serial flash. CCS Project: spi_serialflash

C File Only: spi_serialflash.c

The table you included contrasting the SPI and SSI doesn't look correct, there aren't 2 CLK signals for SSI, the SSInFss works similar to a chip select. More info can be found in our Technical Reference Manual for the MSP432E4 section 23 for the QSSI module.

Regards,

Luke
