hello Developers,
What is the desired frequency for running Qspi in 5MHz Baudrate.

frequency fbaud2 ---- ?
frequency SPB fSPB ----?

Kindly shed some light.

Kind Regards,
Deepak

fBAUD2 can be faster, slower, or equal to fSPB
fsource can be either the fPLL or the Backup Clock
fBAUD2 = fsource / CCUCON0.BAUD2DIV

Using the TC27x, typically fPLL = 200MHz is the fsource and setting CCUCON0.BAUD2DIV=1 then fBAUD2 = 200MHz; fSPB = 100MHz

For a 5MHz SCLK frequency you can choose: TQ=0, Q=4, A=3, B=1, C=3

Hello deepakseshan1,

In addition, you can find a code example project that shows how to configure and use the QSPI module here: QSPI training code example.
this example also comes with a tutorial, which can be found here: QSPI tutorial.

If you are interested in other modules and you want to start programming for AURIX™, you can get the new Integrated Development Environment (IDE) here: AURIX™ Development Studio and get inspired by numerous trainings from here:AURIX™ Trainings.

If you are not familiar with Eclipse based IDE’s checkout the Getting Started guide!

Hope it helps,

Hello All,
I am working on QSPI, I wanted implement this below configuration with iLLD, Is it possible?
For a 5MHz SCLK frequency you can choose: TQ=0, Q=4, A=3, B=1, C=3"

Kindly can you help me on following questions,

1) how to use the QSPI data transfer without iLLD for the above configuration?
2) How to use the BACON register away from iLLD.

I believe you can shed some light to me on this topic,

Thank you in advance,

Kind Regards,
Deepak
