Table 98:
This command unlocks ISP1161A’s DC 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 firmware must unlock the registers and
FIFOs via this command, by writing the unlock code (AA37H) into the Lock register.
The bit allocation of the Lock register is given in
Code (Hex): B0 — unlock the device
Transaction — write 1 word (unlock code)
Table 100: Lock register: bit description
This command accesses the 16-bit DcScratch register, which can be used by the
firmware to save and restore information, e.g., the device status before powering
down in ‘suspend’ state. The register bit allocation is given in
