TMS570LC4357: Discrepancy in MSTGENA Field Descriptions for Memory Self-Test Controller Global Enable Key

Part Number: TMS570LC4357

Tool/software:

Hello,

I think i have identified a discrepancy in the documentation of the MSTGENA field descriptions for the Memory Self-Test Controller Global Enable Key. This needs to be reviewed and corrected to align with the intended functionality and ensure clarity for developers.

SPNU563A–March 2018

Table 2-39. Memory Self-Test Global Control Register (MSTGCR) Field Descriptions

Discrepancy Details:

  • Current Documentation:

    • The documentation specifies:
      Ah Memory self-test controller is enabled
      Others Memory self-test controller is disabled.
      
    • Note included:
      Note: It is recommended that a value of Ah be used to disable the memory self-test
      controller. This value will give maximum protec...
      
  • Issue:

    • There is a contradiction in the documentation regarding the value 'Ah'. Initially, it states that the value 'Ah' enables the memory self-test controller. However, the note later suggests that the value 'Ah' should be used to disable the memory self-test controller.
    • The end of the note is cut off, making the recommendation incomplete

  • Hi mc b,

    • There is a contradiction in the documentation regarding the value 'Ah'. Initially, it states that the value 'Ah' enables the memory self-test controller. However, the note later suggests that the value 'Ah' should be used to disable the memory self-test controller.
    • The end of the note is cut off, making the recommendation incomplete

    You are totally correct about this issue it is a typo and here in the note section it should be 5h not Ah.

    Even i verified in other similar Hercules controller TRM and there i could see 5h.

    Thanks for bringing this to our notification, i will log this document typo and will rectify it in our future version releases.
