8.2.3.9.5 SET EAS

Command code = A2h

The SET EAS command enables the EAS mode if the EAS mode is not locked.

If the EAS mode is password protected the EAS password has to be first transmitted with

the SET PASSWORD command.

If AES authentication scheme is enabled and EAS mode is protected, a valid mutual

authentication with a key with the EAS/AFI privilege set has to executed before.

The timing of the command is write alike.

Option_flag = 0b and Option_flag = 1b is supported and is in accordance with ISO/IEC

15693 write-alike commands.
