LRIS2K

Lock Block

61/102

Lock Block

On receiving the Lock Block command, the LRIS2K permanently locks the selected block.

The Option_flag is supported.

During the write cycle tW, there should be no modulation (neither 100% nor 10%).

Otherwise, the LRIS2K may not lock correctly the memory block. The tW time is equal to

t1nom + 18 × 302µs.
