This 16-bit register can be used by the firmware to save and restore information. For
example, the device status before it enters the suspend state; see
To protect registers from getting corrupted when the SAF1761 goes into suspend, the
write operation is disabled. In this case, when the chip resumes, the Unlock Device
command must first be issued to this register before attempting to write to the rest of the
registers. This is done by writing unlock code (AA37h) to this register. The bit allocation of
the Unlock Device register is given in
