blocks (see WRITE_BL_LEN). The actual size is computed by increasing this number by one. A value of zero means 1
write block, 127 means 128 write blocks.
•
The size of a write protected group. The contents of this register is a 7 bit binary coded value, defining the number of
erase sectors (see SECTOR_SIZE). The actual size is computed by increasing this number by one. A value of zero
means 1 erase sector, 127 means 128 erase sectors.
•
A value of ‘0’ means no group write protection possible.
•
Defines the typical block program time as a multiple of the read access time. The following table defines the field format.
•
The maximum write data block length is computed as 2
the range from 512 up to 2048 bytes. Write Block Length of 512 bytes isalways supported.
Note that in SD Memory Card the WRITE_BL_LEN is always equal to READ_BL_LEN.
