The different errors that can occur in this module.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Response

A transmit bit error, end bit error, or CMD index error has occurred.

ResponseCrc

Invalid CRC in response.

DataCrc

When receiving data, this means that the received data has data CRC error. When transmitting data, this means that the received CRC status taken is negative.

ResponseTimeout

Did not receive a response in time.

DataTimeout

Did not receive data in time.

DataStarvationTimeout

Data starvation detected.

FifoUnderrunOverflow

FIFO underrun or overflow.

CommandBusyIllegalWrite

Command busy and illegal write. TODO: understand this + add better explanation

DataStart

When receiving data, this means that the host controller found an error start bit. When transmitting data, this means that the busy signal is cleared after the last block.

DataEnd

When receiving data, this means that we did not receive a valid data end bit. When transmitting data, this means that we did not receive the CRC status token.

Dma

An error occurred in the internal DMA controller.

Other

A different error occurred. The original error may contain more information.
