ACMD12CRCER
1’h0
ROC
Occurs when detecting a CRC error in the
command response.
1’b0 - No Error
1’b1 - CRC Error Generated
[01]
ACMD12TOER
1’h0
ROC
Occurs if the no response is returned. within 64
SDCLK cycles from the end bit of the
command. If this bit is set to logic ‘1’, the other
error status bits (bit 4:2) are meaningless.
1’b0 - No Error
1’b1 - Timeout
[00]
ACMD12NEX
1’h0
ROC
If memory multiple block data transfer is not
started due to command error, this bit is not set
because it is not necessary to issue Auto
CMD12. Setting this bit to logic ‘1’ means the
HC cannot issue Auto CMD12 to stop memory
multiple block transfer due to some error. If this
bit is set to logic ‘1’, other error status bits (4:1)
are meaningless.
