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 ATA5567 extended mode options,
even when the X-mode bit is set.
• 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.
