We are investigating to use the burst interface of the LPSPI module of the S32K3xx MCU.
Is there any information or any example projects available that use this burst interface (TCBR, TDBR[0..127], RDBR[0..127] registers). The reference manual only writes that they are an alias of the normal registers (TCR, TDR and RDR) but there seems to be no information on how they can/should be used.
Some more specific questions:
Hi Joost,
here is the feedback I just got:
"The TDBR is an alias, writing to any of those addresses is identical to writing to the TDR. There is no TDBR pointer or memory.
There are 2 main uses for this register:
So you can use those registers as the normal ones."

@lukaszadrapathanks for the answer.
Is it possible to ask for an Reference Manual update to include this explanation. Furthermore would it be possible to add a simple example in the reference manual explaining the use of these burst registers.
Sure, I will ask for that.
@lukaszadrapado you have an update on this?
I'm also investigating the use of the TDBR register.
Hi Rob,
not yet. It was forwarded to design team and I'm afraid it will take a couple of days.

Hi Joost,
I had to ask for the details because it's really missing in the reference manual. I'm afraid it will take more time. I will let you know later. Thanks for patience.
