TRM mentions:
"MMC command/response sets as defined in the MMC standard specification v4.3."
"The restriction is a result of many eMMC devices not being compliant with the eMMC v4.41 specification."
I understand that MMC and eMMC comply with the following JEDEC standards respectively.
For the MMC standard specification v4.3: JESD84-A43
https://www.jedec.org/standards-documents/docs/jesd-84-a43
For the eMMC v4.41 specification: JESD84-A441
https://www.jedec.org/standards-documents/docs/jesd84-a441
Is my understanding correct?
Best regards,
Daisuke
