Preliminary - Revision B
7.2.12 Program Suspend/Resume
Once a program operation is in progress, a Program Suspend is the only valid instruction that maybe
executed. Verifying if the device has entered the Program-Suspend Read mode after executing the
Program-Suspend instruction, can be done by checking the RY/#BY and DQ6. Programming should
halt within 15s maximum (5s typical).
Any sector(s) can be read except those being program suspended. Trying to read a sector being
program suspended is invalid. Before another program operation can be executed, a Resume
instruction must be performed and DQ6 toggling bit status has to be verified. Use the status register
bits shown in the following table to determine the current state of the device:
Status
DQ7 DQ6 DQ5 DQ3 DQ2 DQ1 RY/#BY
Program suspend read in program suspended sector
Invalid
1
Program suspend read in non-program suspended sector

Polling During Embedded Program Suspend
Instruction sets such as read silicon ID, sector protect verify, program, CFI query can also be executed
during Program/Erase-Suspend mode.
7.2.13 Program Resume
The program Resume instruction is valid only when the device is in Program-Suspended mode. Once
the program resumes, another Program Suspend instruction can be executed. Insure there is at least
a 5s interval between Program Resume and the next Suspend instruction.
7.2.14 Programming Operation
Write Buffer Programming Operation, programs 32-bytes or 16-words in a two step programming
operation. To begin execution of the Write Buffer Programming, start with the first two unlock cycles,
the third cycle writes the programming Sector Address destination followed by the Write Buffer Load
Instruction (25h). The fourth cycle repeats the Sector Address, while the write data is the number of
intended word locations to be written minus one. (Example, if the number of word locations to be
written is 9, then the value would be 8h.) The 5
th cycle is the first starting address/data set. This will be
the first pair to be programmed and consequentially, sets the “write-buffer-page” address. Repeat
Cycle 5 format for each additional address/data sets to be written to the buffer. Keep in mind all sets
must remain within the write buffer page address range. If not, operation will ABORT.
The “write-buffer-page” is selected by choosing address A[20:5].
The second step will be to program the contents of the write buffer page. This is done with one cycle,
containing the sector address that was used in step one and the “Write to Buffer Program Confirm”
instruction (29h).
Standard suspend/resume commands can be used during the operation of the write-buffer. Also, once
the write buffer programming operation is finished, it’ll return to the normal READ mode.
Write buffer programming can be conducted in any sequence. However the CFI functions, autoselect,
Secured Silicon sector are not functional when program operation is in progress. Multiple write buffer
programming operations on the same write buffer address range without intervention erase is
accessible. Any bit in a write buffer address range cannot be programmed from 0 back to 1.
