Preliminary product information describe products that are in development,
for which full characterization data and associated errata are not yet available.
Specifications and information herein are subject to change without notice.
ERROR INTERRUPT STATUS REGISTER
Signals defined in this register can be enabled by the
Error Interrupt Status Enable
register, but not by the
Error Interrupt Signal Enable
register. The interrupt is generated when 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 can be cleared at the one register write.

ADMAER
R
[9]
ADMA Error
This bit is set when 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 when 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
0
STAACM
DERR
[8]
Auto CMD12 Error
Occurs when detecting that one of the bits in
Auto CMD12 Error Status
register has changed from 0 to 1. This bit is set to 1,not only when the errors
in Auto CMD12 occur but also when Auto CMD12 is not executed due to the
previous command error.
‘1’ = Error
‘0’ = No Error
0

STADEN
DERR

Data End Bit Error
Occurs either when detecting 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
0
STADAT

[5]
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".
‘1’ = Error
‘0’ = No Error
0
STADAT
TOUTER
[4]
Data Timeout Error
Occurs when detecting one of following timeout conditions.
(1) Busy timeout for R1b,R5b type
0
