Appendix B: Register Details
reserved 27:26 ro 0x0 Reserved
ADMA_Error 25 wtc 0x0 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.
1- Error
0 -No error
Auto_CMD12_Error 24 wtc 0x0 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 also when Auto CMD12 is
not executed due to the previous command error.
0 - No Error
1 - Error
Current_Limit_Error 23 wtc 0x0 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 1 means the HC is not supplying
power to SD card due to some failure. Reading 0
means that the HC is supplying power and no
error has occurred. This bit shall always set to be
0, if the HC does not support this function.
0 - No Error
1 - Power Fail
Data_End_Bit_Error 22 wtc 0x0 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.
0 - No Error
1 - Error
Data_CRC_Error 21 wtc 0x0 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'.
0 - No Error
1 - Error
Data_Timeout_Error 20 wtc 0x0 Occurs when detecting one of following timeout
conditions.
1. Busy Timeout for R1b, R5b type.
2. Busy Timeout after Write CRC status
3. Write CRC status Timeout
4. Read Data Timeout
0 - No Error
1 - Timeout
