3. Wait for the NAND device to complete accessing the block data by watching the ready
signal.
4. Check for NAND timeout through "PSENSE".
5. Configure and enable the BCH block and read the NAND block data.
6. Disable the BCH block.
7. Descriptor NOP to allow NANDLOCK in the previous descriptor to the thread-safe.
