Lock Password
On receiving the Lock Password command, the LRIS2K sets the access rights and
permanently locks the selected block. The Option_flag is supported.
RFU bit 8 of the request_flag is used to select either the memory area (bit 8 = ‘0’) or the
password area (bit 8 = ‘1’).
During the write cycle t
the LRIS2K may not correctly lock the memory block.
The t
