Error
Bit 7 – CURLIM Current Limit Error
By setting SD Bus Power (SDBPWR) in PCR, the peripheral is requested to supply power for the SD Bus.
The peripheral is protected from an illegal card by stopping power supply to the card, in which case this
bit indicates a failure status. Reading 1 means the peripheral is not supplying power to the card due to
some failure. Reading 0 means that the peripheral is supplying power and no error has occurred. The
peripheral may require some sampling time to detect the current limit.
This bit can only be set to 1 if EISTER.CURLIM is set to 1. An interrupt can only be generated if
EISIER.CURLIM is set to 1.
Writing this bit to 1 clears this bit.
Value Description
0
No error
1
Error
Bit 6 – DATEND Data End Bit Error
This bit is set to 1 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.
This bit can only be set to 1 if EISTER.DATEND is set to 1. An interrupt can only be generated if
EISIER.DATEND is set to 1.
Writing this bit to 1 clears this bit.
Value Description
0
No error
1
Error
Bit 5 – DATCRC Data CRC Error
This bit is set to 1 when detecting a CRC error during a transfer of read data which uses the DAT line or
when detecting that the Write CRC Status has a value other than '010'.
This bit can only be set to 1 if EISTER. DATCRC is set to 1. An interrupt can only be generated if EISIER.
DATCRC is set to 1.
Writing this bit to 1 clears this bit.
Value Description
0
No error
1
Error
Bit 4 – DATTEO Data Timeout error
This bit is set to 1 when detecting one of following timeout conditions:
Busy timeout for R1b, R5b response type (see “Physical Layer Simplified Specification V3.01” and
“SDIO Simplified Specification V3.00” ).
Busy timeout after Write CRC Status.
Write CRC Status timeout.
Read data timeout.
This bit can only be set to 1 if EISTER.DATTEO is set to 1. An interrupt can only be generated if
EISIER.DATTEO is set to 1.
Writing this bit to 1 clears this bit.
