Defines the typical block program time as a multiple of the read access time. The following table defines
the field format.

This parameter value is 4 for these MultiMediaCards.
WRITE_BLK_LEN
Block length for write operation. See READ_BL_LEN for field coding.
WRITE_BLK_PARTIAL
WRITE_BLK_PARTIAL defines whether partial block sizes can be used in block wrtie commands.
WRITE_BLK_PARTIAL = 0 means that only the block size defined by WRITE_BLOCK_LEN can be used
for block-orinted data transfer. WRITE_BLK_PARTIAL = 1 means that smaller blocks can be used as
well. The minimum block size will be equal to minimum addressable unit (one byte). These
MultiMediaCards support partial block read. The parameter WRITE_BLK_PARTIAL is permanently
assigned to the value “0”.
FILE_FORMAT_GRP
Indicated the selected group of file formats. This fiels is read-only for ROM. The usage of this fiels is
shown in table “File_Formats”
COPY
Defines if the contents are an original (= 0) or a copy (= 1). The COPY bit is a one time programmable bit,
being set by the customer.
PERM_WRITE_PROTECT
Permanently protects the whole card content against overwriting or erasing (all write and erase
commands for this card is a permanently disabled). This parameter is one-time programmable by the
customer. The default value is ‘0’ (not 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 parameter is programmable by the customer. The
default value is ‘0’ (not protected).
