First command cycle address should be the same as the operation’s target address. DBA = Device Base Address (NOTE: needed for dual-die 512 Mb device) DnA = Address within the device. IA = Identification code address offset. CFI-A = Read CFI address offset. WA = Word address of memory location to be written. BA = Address within the block. OTP-RA = Protection Register address. LRA = Lock Register address. RCD = Read Configuration Register data on QUAD+ A[15:0] or EASY BGA A[16:1]. 2. ID = Identifier data. CFI-D = CFI data on DQ[15:0]. SRD = Status Register data. WD = Word data. N = Word count of data to be loaded into the write buffer. OTP-D = Protection Register data. LRD = Lock Register data. 3. The second cycle of the Buffered Program Command is the word count of the data to be loaded into the write buffer. This is followed by up to 32 words of data.Then the confirm command (0xD0) is issued, triggering the array programming operation. 4. The confirm command (0xD0) is followed by the buffer data. |
