RM48L952: Errata DEVICE#140 and Errata Documentation

Part Number: RM48L952
Other Parts Discussed in Thread: HALCOGEN,

Hello,

I was looking at HALCoGen generated code, and noticed this errata:

/* Work Around for Errata DEVICE#140: ( Only on Rev A silicon) 
 *
 * Errata Description:
 *            The Core Compare Module(CCM-R4) may cause nERROR to be asserted after a cold power-on
 * Workaround:
 *            Clear ESM Group2 Channel 2 error in ESMSR2 and Compare error in CCMSR register */
if (DEVICE_ID_REV == 0x802AAD05U)
{
    _esmCcmErrorsClear_();
}

I cannot find any details about this errata in these documents listed here: http://www.ti.com/product/RM48L952/technicaldocuments#doctype3

There are two errata's listed,
RM48x Microcontroller Silicon Errata (Silicon Revision D) (Rev. B)
and
RM48x Microcontroller Silicon Errata (Silicon Revision C) (Rev. G)

Is there any way to view the errata for Silicon revision B and A for the RM48L952?

Thanks

    Hello Brian,

    We only maintain the Errata documents for silicon revisions that were put into production. Silicon Rev.A was only shipped as pre-production material and would only have been included on development boards during early prototype production and sampling.

    For your convenience and understanding, I have included the excerpt from the Rev.A silicon errata below that explains Device#140. This issue was repaired in the subsequent silicon revisions starting with Silicon Revision B.
