TMS570LS1224 SPI Queries

Other Parts Discussed in Thread: TMS5701224

Hi 

We are using TMS5701224CPGEQQ1in our design. 

We have interfaced, M95M04-DWDW4TP/V (EEPROM) over SPI4 of the TMS5701224. 
Can we use another SPI based device over the same port with different CS pin?
Will it work properly without any issue? 

Thanks!

    Hi Swadesh,

    Yes. There is no problem to connect different device on to a separate CS pin.

    Each SPI may have several CS pins which are used when communicating with multiple slave devices. When the a write occurs to SPIDAT1 in master mode, the SPISCS pins are automatically driven to select the specified slave.
