Description

FMC NAND command sequencer configuration register 2

Fields

SQSDTEN

Sequencer spare data transfer enable

0 (B_0x0): ECC disabled and spare data area not accessed by the sequencer

1 (B_0x1): ECC enabled and spare data area read or programmed by the sequencer after each sector transfer

RCMD2EN

Random Command 2 sequencer enable

0 (B_0x0): Command 2 not issued.

1 (B_0x1): Command 2 (CMD2SQ[7:0]) issued by the command sequencer to NAND flash memory after the address cycle.

DMASEN

Command sequencer DMA request decoding status enable

0 (B_0x0): No DMA request used for ECC status registers transfer

1 (B_0x1): A DMA request used for ECC status registers transfer

RCMD1
