Notes/Warnings
...
...
  1. The device must be a NOR device (e.g., 
...
  1. “nor:0:”).
...
  1. Care should be taken if this function is used while a file system exists on the device, or if the device is low-level formatted. The octet location(s) modified are not validated as being outside any existing file system or low-level format information.
...
  2. During a program operation, only 1 bits can be changed; a 0 bit cannot be changed to a 1. The application must know that the octets being programmed have not already been programmed.
