Description
Card status response error
This register enables the host controller to detect card status errors of response type R1, R1b for all cards
and of R5, R5b and R6 response for cards types SD or SDIO.
When a bit MMCi.
[I] is set to 1, if the corresponding bit at the same position in the response
[I] is set to 1, the host controller indicates a card error (MMCi.
CERR bit) interrupt status to avoid the host driver reading the response register (MMCi.
Note: No automatic card error detection for autoCMD12 is implemented; the host system has to check
autoCMD12 response register (MMCi.
) for possible card errors.
