ATA555815-PAE 数据手册

ATA5558 [Preliminary]

To access a protected memory block, a Login command with the corresponding read or write

password had to be executed once per session. During the login procedure the 32-bit password

field of the login command is compared with the contents of the corresponding password in the

system memory. If the passwords match, the ATA5558 tag will return an SOF pattern as an

acknowledge signal. If they do not match, the tag will respond with an SOF followed by the

appropriate error code. Writing to a protected memory address which has not been enabled with

the correct LoginWrite password, will result in an error code on completion of the interrogator

command. Reading a password protected memory address which has not been enabled with

the correct LoginRead password, returns a block of all

data and no error code.
