Query on DSPI implementation in S32G3 processor

Hello team,

I have seen DSPI implementations available in AN2867 (Using the DSPI Module on the MPC5500 Family, Rev. 0) and "MPC5607B Microcontroller Reference Manual, Rev. 7.1". I could note from these that DSPI is Deserial Serial Peripheral Interface. Then I came across a document hosted on NXP website (https://www.nxp.com/docs/pcn_attachments/15174_DSPI-table.pdf) where it is stated as DMA Serial Peripheral Interface (DSPI). Could you let me know for my understanding that what it takes for differentiating the same? Also, what will we call (full-form) on the DSPI implementation provided on S32G3 and why de-serial block could be omitted from block diagram if it is Deserial Serial Peripheral Interface? This is because the S32G3 reference manual shows only SPI block in DSPI block diagram with its pin-outs referring to the DSPI notation.

Hi，kishanmishra

Thank you for contacting us.

According to the chapter 2.4 of S32G2RM.pdf, The DSPI is described De-serial Serial Peripheral Interface in the Communication interface. I suppose you can refer to the description and I will ask in internal about the question for you.
