These bits are always read as 0. The write value should
always be 0.
Write Error Flag
[Setting condition]
When a status error for transmit data response (write
error) is detected while WREIE = 1.
[Clearing condition]
Write 0 after reading WREI = 1.
Note: When the write error occurs, halt the command
CRC Error Flag
[Setting condition]
When a CRC error for command response or receive
data, and CRC status error for transmission data
response are detected while CRCERIE = 1.
For any non-R2 command response, CRC is checked
when the RTY4 in RSPTYR is set for enabling.
For the R2 command response, CRC is not checked;
therefore, this flag is not set.
[Clearing condition]
Write 0 after reading CRCERI = 1.
Note: When the CRC error occurs, halt the command
Data Timeout Error Flag
[Setting condition]
When a data timeout error specified in DTOUTR occurs
while DTERIE = 1.
[Clearing condition]
Write 0 after reading DTERI = 1.
Note: When the data timeout error occurs, clear the
sequence by setting the CMDOFF bit to 1.
sequence by setting the CMDOFF bit to 1.
DTERI flag after halting the command sequence
by setting the CMDOFF bit to 1.
