RM48L940: L2L3 Register Readback

Intellectual 600 points

Part Number: RM48L940

Same question as here:

https://e2e.ti.com/support/microcontrollers/hercules/f/312/t/585578?TMS570LS0332-Regarding-register-read-back-feature-of-L2L3-configuration-registers

and here

https://e2e.ti.com/support/microcontrollers/hercules/f/312/t/604393?RM41L232-Level-2-Level-3-L2-L3-Interconnect

but for the RM48. 

How do I define l2l3_config_reg (I understand I can define it similar to pcr)?

How do I implement l2l3GetConfigValue() so that I can baseline the register?

Are the registers dynamic and expected to change during runtime??

 

  • Hi Guy,

    Guy Tadi
    How do I define l2l3_config_reg (I understand I can define it similar to pcr)?

    >>As mentioned by QJ in the 2nd e2e thread, the l2l3_config_reg is same as the pcr_config_reg_t. 

    Please refer to the Safety Manual for RM48 : http://www.ti.com/lit/ug/spnu577d/spnu577d.pdf

    How do I implement l2l3GetConfigValue() so that I can baseline the register?

    >>Please use the pcrGetConfigValue as you can read back the values of PCR registers only as these are the only registers accessible.

          1.The default value in the registers is zero before the core initialization. You could use this as a baseline or,

          2. Read back the registers after the core initialization before the main application starts.

    Are the registers dynamic and expected to change during runtime??

    >> Due to peripheral initialization and also based on your application, the register values will be modified.

    Thanks,
