1. n+1 is the number of addresses to be programmed.
2. A write to buffer program abort and reset must be issued to return the device in read mode.
3. When the block address is specified, any address in the selected block address space is acceptable. However when

location is reached because DQ1=’1’, then the Write to Buffer Program command aborted. In both cases, the appropriate
reset command must be issued to return the device in read mode: a Reset command if the operation failed, a Write to
Buffer Program Abort and Reset command if the operation aborted.
