RM48L952: Which registers are the Reset Configuration registers (RST6/7)

K De Coster

Part Number: RM48L952

Hello there,

In the Safety manual for RM48 [SPNU577d] safety feature or diagnostic RST6 and RST7 describe "Periodic software readback of static configuration registers" and " Software readback of written configuration".
I do not know which configuration registers are meant here. I do not think CPURSTCR is meant here. Can you give me tell me which registers are meant here?

Thanks in advance,

Karel

Hello Karel,

Please refer to the following thread about the static configuration registers:

e2e.ti.com/.../2094657

You need to identify the registers that are deem critical to your application. CPUSTCR is CPU STC registers (CPU self test).

Hello QJ Wang,

Thanks for your response.
I have found the thread and from our application we have determined that reset is safety critical.
I know the registers are in the TRM, I cannot determine which configuration registers are related to the RST6/RST7.
For real peripherals (for example SPI) it is clear that the configuration registers of the SPI are listed in the SPI Chapter of the TRM. However as RST is not a "real peripheral" it has not have its own chapter in the TRM. Because of this I do not know which registers are meant here.

Best regards,

Karel
