20.4.13 Auto CMD12 Error Status Register (AUTOC12ERR)
When IRQSTAT[AC12E] is set, the host driver checks this register to identify what kind of error Auto
CMD12 indicated. This register is valid only when IRQSTAT[AC12E] is set.
Offset: 0x03C (AUTOC12ERR)

Command not issued by Auto CMD12 error. This bit is set when CMD_wo_DAT is not executed due to an
Auto CMD12 error (D04–D01).

Auto CMD12 index error. Occurs if the command index error occurs in response to a command.
0 No error
1 Error, the CMD index in response is not CMD12
Auto CMD12 CRC error. Occurs when detecting a CRC error in the command response.
0 No CRC error
1 CRC error met in Auto CMD12 response
Auto CMD12 end bit error. Occurs when detecting that the end bit of command response is 0 when it should
be 1.
0 No error
1 End bit error generated
Auto CMD12 timeout error. Occurs if no response is returned within 64 SDHC_CLK cycles from the end bit
of the command. If this bit is set, the other error status bits (2–4) are meaningless.
0 No error
1 Time out
Auto CMD12 not executed. If a 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 means eSDHC cannot
issue Auto CMD12 to stop the memory multiple block data transfer due to some error. If this bit is set, the
other error status bits (1–4) are meaningless.
