Part Number: MSP430F427
We have a customer asking if we can connect MSP430 to another device which only support dual SPI mode using SPI interface?None of the msp430 documents says it support Dual SPI mode.
unfortunately none of the MSP430 devices support dual mode operation of SPIs.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Peter Spevak:
How about for MSP432? According to MSP432E411 it supports "Four Quad Synchronous Serial Interface (QSSI): With Bi-, Quad-, and Advanced-SSI Support"
What does this mean? Is it same as SPI? Do you have any specific document and examples for MSP432 QSSI?Our customer wants to connect a microcontroller to another SPI device which support only DUAL and Quad SPI. The SPI slave device which I want to connect can be configured only as Dual or Quad SPI mode and not in standard mode.
Appreciate your advice.
In reply to Roland Melad:
The E series supports Quad (and subsets) SPI/SSI. The P series doesn't. I suppose they called it SSI since, by the time you've redefined that many pins, it doesn't look much like SPI any more. [Disclaimer: I haven't so far used the QSSI mode, only the SPI "Legacy" mode.]
In reply to Bruce McKenney47378:
this is sort of also my understanding. The MSP432E411 supports these legacy modes, where SPI should be supported including dual and quad mode. The SSI interface as such is somewhat additional, as balanced communication (+/-).
The MSP432P4xx is in very detail a completely different device family, basically equipped with MSP430 modules, like the eUSCI in case of serial communication, and thus also only supporting the same features like an MSP430 device, means in this case not supporting the dual and quad mode SPI.
