Unlock Device
This command unlocks the ISP1181B from write-protection mode after a ‘resume’. In
‘suspend’ state all registers and FIFOs are write-protected to prevent data corruption
by external devices during a ‘resume’. Also, the register access for reading is possible
only after the ‘Unlock Device’ command is executed.
After waking up from ‘suspend’ state, the rmware must unlock the registers and
FIFOs via this command, by writing the unlock code (AA37H) into the Lock Register
(8-bit bus: lower byte rst). The bit allocation of the Lock Register is given in Table 38.
Code (Hex): B0 — unlock the device
Transaction — write 2 bytes (unlock code)
