This command unlocks the Peripheral Controller from write-protection mode after a
‘resume’. In the ‘suspend’ state, all registers and buffer memory are write-protected to
prevent data corruption by external devices during a ‘resume’. Also, the register access to
read is possible only after the ‘unlock device’ command is executed.
After waking up from the ‘suspend’ state, firmware must unlock registers and buffer
memory by using this command, by writing the unlock code (AA37h) into the DcLock
register (8-bit bus: lower byte first). The bit allocation of the DcLock register is given in
Table
Code (Hex): B0 — unlock the device
Transaction — write 2 bytes (unlock code) (code or data)
Table 133. DcLock register: bit description
This command accesses the 16-bit DcScratch register, which can be used by firmware to
save and restore information. For example, the device status before powering down in the
‘suspend’ state.
The register bit allocation is given in
Code (Hex): B2/B3 — write or read DcScratch register
Transaction — write or read 2 bytes (code or data)
