ACMD12ERR 1’h0
RW1C
Auto CMD12 Error
Occurs when detecting that one of the bits in
AutoCMD12 Error Status register has changed
from 0 to 1. This bit is set to logic ‘1’ also when Auto
CMD12 is not executed due to the previous
command error.
1’b0 - No Error
1’b1 - Error

CURLERR
1’h0
RW1C
Current Limit Error
By setting the SD Bus Power bit in the Power
Control Register, the HC is requested to supply
power for the SD Bus. If the HC supports the
Current Limit Function, it can be protected from an
Illegal card by stopping power supply to the card in
which case this bit indicates a failure status.
Reading logic ‘1’ means the HC is not supplying
power to SD card due to some failure. Reading
logic ‘0’ means that the HC is supplying power and
no error has occurred. This bit shall always set to
be logic ‘0’, if the HC does not support this function.
1’b0 - No Error
1’b1 - Power Fail

RW1C
Data End Bit Error
Occurs when detecting 0 at the end bit position of
read data which uses the DAT line or the end bit
position of the CRC status.
1’b0 - No Error
1’b1 - Error

1’h0
RW1C
Data CRC Error
Occurs when detecting CRC error when
transferring read data which uses the DAT line or
when detecting the Write CRC Status having a
value of other than “010”.

Data Timeout Error
Occurs when detecting one of following timeout
conditions:
Busy Timeout for R1b, R5b type.
Busy Timeout after Write CRC status
Write CRC status Timeout
Read Data Timeout
1’b0 - No Error
1’b1 - Timeout
