Description:
 def protect(self, password=None, read_protect=False, protect_from=0):
 """Set password protection or permanent lock bits. If the *password* argument is None, all memory pages will be protected by setting the relevant lock bits (note that lock bits can not be reset). If valid NDEF management data is found, protect() also sets the NDEF write flag to read-only. All Tags of the NTAG21x family can alternatively be protected by password. If a *password* argument is provided, the protect() method writes the first 4 byte of the *password* string into the Tag's password (PWD) memory bytes and the following 2 byte of the *password* string into the password acknowledge (PACK) memory bytes. Factory default values are used if the *password* argument is an empty string. Lock bits are not set for password protection. The *read_protect* and *protect_from* arguments are only evaluated if *password* is not None. If *read_protect* is True, the memory protection bit (PROT) is set to require password verification also for reading of protected memory pages. The value of *protect_from* determines the first password protected memory page (one page is 4 byte) with the exception that the smallest set value is page 3 even if *protect_from* is smaller. """
