By default, the EAS configuration (EAS telegram, EAS ID, EAS configuration, lock EAS, EAS mode) is not write

protected.

The EAS configuration can be write protected by the configuration password (PWD_CFG) by writing 1b1 into the

W_PROTECTION_EAS (EAS_SEC register). If W_PROTECTION_EAS bit is set, the EAS configuration can be

changed only if the configuration password has been presented just before in the same RF session.

Write access to the EAS configuration can be locked by executing the lock_EAS command. User cannot unlock

system configuration if the EAS configuration has already been locked earlier with the Lock_EAS command, even

after opening configuration security session (Lock is definitive).
