SIZE_OF_PROTECTED_AREA
Setting this field differs between standard- and high-capacity cards. In the case of a
standard-capacity card, the capacity of protected area is calculated as follows:
In the case of a high-capacity card, the capacity of protected area is specified in this field:

In the future, the 8 LSBs will
be used to define different
variations of an SD memory
card (each bit will define
different SD types). The 8
MSBs will be used to define
SD Cards that do not comply
with current SD physical
layer specification.
