Description
Reserved
These bits are always read as 0. The write
value should always be 0.
[Setting 1 condition]
When a status error (write error) for
transmit data response is detected while
WREIE = 1.
[Clearing 0 condition]
Write 0 after reading WREI = 1.
Note:
[Setting 1 condition]
When a CRC error for command response
or receive data or a CRC status error for
transmit data response is detected while
CRCERIE = 1.
For the command response other than R2,
CRC is checked when the RTY4 in
RSPTYR is enabled.
For the R2 command response, CRC is
not checked, thus this flag is not set.
[Clearing 0 condition]
Write 0 after reading CRCERI = 1.

When the write error occurs,
abort the command sequence by
setting the CMDOFF bit to 1.
When the CRC error occurs,
abort the command sequence by
setting the CMDOFF bit to 1.
