Load some data into the Data RAM memory in MC33PT2000?

[Borden]

MC33PT2000, During program execution, need to modify some data in DATARAM. While debugging, it was discovered that rewriting all 192 data  to DATARAM was the only effective method. Is it possible to change a specific data in DATARAM Using a simple method? How can the code be written?

Dear Hongyu,

the DataRAM access is described in the section 2.8 in the PT2000SWUG attached. Please refer to it.

Thank you! But, I didn't describe it clearly. Actually, I want to enable real-time data exchange between the microcontroller (for example: S32K144) and the MC33PT2000 (writing data to DATARAM). What method should I use?

Dear Hongyu,

please use the PSC simulator. Please check the videos in this link. Please also check the section 8.1.2.2 in the PT2000 datasheet.
