COPY

Defines if the contents is original (= ‘0’) or has been copied (=’1’). The COPY bit for OTP and MTPdevices, sold to end consumers, is set to ‘1’ which identifies the card contents as a copy. The COPY bit is an one time programmable bit.

PERM_WRITE_PROTECT

Permanently protects the whole card content against overwriting or erasing (all write and erase commands for this card are permanently disabled). The default value is ‘0’, i.e. not permanently write protected.

TMP_WRITE_PROTECT

Temporarily protects the whole card content from being overwritten or erased (all write and erase commands for this card are temporarily disabled). This bit can be set and reset. The default value is ‘0’, i.e. not write protected.

FILE_FORMAT

This field is set to 0. Host should not use this field.

CRC

The CRC field carries the check sum for the CSD contents.

The checksum has to be recalculated by the host for any CSD modification. The default corresponds to the initial CSD contents.

The following table lists the correspondence between the CSD entries and the command classes. A ‘+’ entry indicates that the CSD field affects the commands of the related command class.
