The properties of write protection are
coded in the card specific data
(WP_GRP_SIZE).

if the card provides write protection
features, this command asks the card
to send the status of the write
protection bits.*¹

Note:
1. 32 write protection bits (representing 32 write protect groups starting at the specified address)
followed by 16 CRC bits are transferred in a payload format via the data line. The last (least
significant) bit of the protection bits corresponds to the first addressed group. If the addresses of
the last groups are outside the valid range, then the corresponding write protection bits shall be
set to zero.
