TDA4VH-Q1: About mmc pin settings

Part Number: TDA4VH-Q1

Tool/software:

Is CTRLMMR_PADCONFIG171 register in the following data sheet a mistake for CTRLMMR_PADCONFIG64 register?

TDA4VH-Q1, TDA4AH-Q1, TDA4VP-Q1, TDA4AP-Q1 JacintoTm Processors datasheet (Rev. B)

J784S4_Registers_20240628.xlsx shows that CTRLMMR_PADCONFIG is only up to 71.

Looking at the device tree, it appears that MMC1_CLKLB is assigned to CTRLMMR_PADCONFIG64 (0x0011C100).

* When the RXACTIVE bit of PADCONFIG64 was 0, the SD card could not be accessed; when it was 1, it could be accessed.

  • Hi Okudera-san,

    I apologize for the delayed response. Thank you for bringing this to our attention!

    Yes, this footnote is incorrect in the datasheet. I reported it internally and we will correct this footnote in the datasheet to reflect PADCONFIG64 and not PADCONFIG171.
