Note:

An external supply (12 V) can be used to improve programming efficiency.

It is possible to detect Program operation fails when changing programmed data from ‘0’ to

‘1’, that is when reprogramming data in a portion of memory already programmed. The

resulting data will be the logical OR between the previous and the current value.

See Appendix D and Figure 29: Enhanced Buffered Program flowchart and pseudocode, for

a suggested flowchart on using the Enhanced Buffered Program command.

Buffered Program Abort and Reset command

A Buffered Program Abort and Reset command must be issued to abort the Write to Buffer

Program and Enhanced Buffered Program operation and reset the device in Read mode.

The write to buffer and enhanced buffered programming sequence can be aborted in the

following ways:

● Load a value that is greater than the page buffer size during the number of locations to

program step in the Write to Buffer Program command

● Write to an address in a block different than the one specified during the write-buffer-

load command

● Write an address/data pair to a different write-buffer-page than the one selected by the

starting address during the write buffer data loading stage of the operation

● Write data other than the Confirm command after the specified number of data load

cycles

● Load address/data pairs in an incorrect sequence during the enhanced buffered

program.

The abort condition is indicated by DQ1 = 1, DQ7 = DQ7 (for the last address location

loaded), DQ6 = toggle, and DQ5 = 0 (all of which are Status Register bits). A Buffered

Program Abort and Reset command sequence must be written to reset the device for the

next operation. Note that the full 3-cycle Buffered Program Abort and Reset command

sequence is required when using write to buffer and enhanced buffered programming

features in Unlock Bypass mode.

Enhanced Buffered Program commands are available for x 16 mode only.
