In general, the block 0 setting of the master key (bits 1 to 4) to the value “6” or “9” together with
the X-mode bit will enable the extended mode functions.
Any other master key setting will prevent the activation of the ATA5570 extended mode options,
even when the X-mode bit is set.
In extended mode the data rate is binary programmable to operate at any data rate between
RF/2 and RF/128 as given in the formula below.
Data rate = RF/(2n + 2)
If the OTP bit is set to “1”, all memory blocks are write protected and behave as if all lock bits are
set to “1”. If, additionally, the master key is set to “6”, the ATA5570 mode of operation is locked
forever (= OTP functionality).
If the master key is set to “9”, the test-mode access allows the re-configuration of the tag.
• Master key = “9”: Test mode access and extended mode are both enabled.
• Master key = “6”: Any test mode access will be denied but the extended mode is still enabled.
