&LP6WDWXV
- Macro command status.
After this byte is read by the application all bits are cleared internally. In case of concur-
rent accesses to any bit, it remains ‘1’. This register can be read by the
CAM_CIM_STATUS command.
Default value is 0x00 (no error).
reserved - returns zero

- MultiMediaCard adapter status.
After this byte is read by the application all bits are cleared internally. In case of concur-
rent accesses to any bit, it remains ‘1’. This register can be read by the
CAM_GET_STATUS command.
Default value is 0x00 (no error).
7LPHRXW'$7
- Timeout on DAT detected
A ‘1’ indicates that ROSA detected a timeout condition while waiting for data on the DAT
line. The timeout value depends on the card’s CSD.
&5&(UURU'$7
- CRC error on DAT detected
A ‘1’ indicates that ROSA detected a CRC error after reading a block of data from the
DAT line.
7LPHRXW&0'
- Timeout on CMD detected
A ‘1’ indicates that ROSA detected a timeout condition while waiting for a response on
the CMD line. The timeout value depends on the type of CMD sent.
&5&(UURU&0'
- CRC error on CMD detected
A ‘1’ indicates that ROSA detected a CRC error after reading a response from the CMD
line.
&6'(UURU
- Bad CSD detected
A ‘1’ indicates that ROSA received a corrupted CSD response.
0PF,UT
