MSP432E401Y: qssi module

Hi,

You can configure the QSSI module to work in Freescale SPI Frame Format. The MSP432E4 Technical Reference Manual can provide further details on the Freescale SPI Frame Format (Section 23.3.7.2).

Hi,

I have one doubt , regrading SSInFSS pin ,

whether ,this pin will go automatically low ,during byte  transfer,

or we need to manually make this pin low,

I  feel confused while reading datasheet.

pls reply

Thanks

Hi Rajeshjumar,

For the freescale format the SSInFSS signal behaves as your peripheral select (peripheral is the slave device). Section 23.3.7.2

And depending on the configuration you choose different settings will be made. I highly suggest looking at this section to understand the different configurations that are available. The term forced is used as it will automatically set, looking at the timing diagrams should help depict it. You can verify this though by looking at the registers through CCS.

Hi, Luke

How to check , qssi is transferring data or not , any methods available apart from

checking register using ccs.

Hi Rajeshkumar,

You should be able to connect an scope to the SSI pins to see the signals on the lines. Below is an image taken from the Datasheet that lists the SSI pins.
