  18           This adds an extra check when data is written to the flash. The
  19           OneNAND flash device internally checks only bits transitioning
  20           from 1 to 0. There is a rare possibility that even though the
  21           device thinks the write was successful, a bit could have been
  22           flipped accidentally due to device wear or something else.

  33           One Block of the NAND Flash Array memory is reserved as
  34           a One-Time Programmable Block memory area.
  35           Also, 1st Block of NAND Flash Array can be used as OTP.
  36
  37           The OTP block can be read, programmed and locked using the same
  38           operations as any other NAND Flash Array memory block.
  39           OTP block cannot be erased.

  41           OTP block is fully-guaranteed to be a valid block.
