Signals defined in this register are enabled by the Error Interrupt Status Enable register, but not by the Error
Interrupt Signal Enable register. Generates interrupt if the Error Interrupt Signal Enable is enabled and at least
one of the statuses is set to 1. Writing to 1 clears the bit and writing to 0 keeps the bit unchanged. More than one
status is cleared on one register write.

[9] ADMA Error
This bit is set if the Host Controller detects errors during ADMA
based data transfer. The state of the ADMA at an error
occurrence is saved in the ADMA Error Status Register, In
addition, the Host Controller generates this Interrupt if it detects
invalid descriptor data (Valid=0) at the ST_FDS state. ADMA
Error State in the ADMA Error Status indicates that an error
occurs in ST_FDS state. The Host Driver may find that Valid bit
is not set at the error descriptor.
'1' = Error
'0' = No Error
[8] Auto CMD12 Error
Occurs if it detects that one of the bits in Auto CMD12 Error
Status register has changed from 0 to 1. This bit is set to 1, if
the errors in Auto CMD12 occur and if Auto CMD12 is not
executed due to the previous command error.
'1' = Error
'0' = No Error
[7] Current Limit Error
Not implemented in this version. Always 0.
[6] Data End Bit Error
Occurs if it detects 0 at the end bit position of read data which
uses the DAT line or at the end bit position of the CRC Status.
'1' = Error
'0' = No Error
[5] Data CRC Error
Occurs if it detects CRC error when transferring read data which
uses the DAT line or if it detects the Write CRC status having a
value of other than "010".
'1' = Error
'0' = No Error
[4] Data Timeout Error
