13.5.4.4
An example of configuring FCM to execute a random page read command to large-page NAND Flash is
shown in
buffer RAM, checking ECC as it proceeds. The sequence is initiated by writing FMR[OP] = 11, and
issuing a special operation to the bank. A few cycles before completion itself, FECCn gets updated with
the ECC bytes for the main region validated by FECCn[0]. At the conclusion of the sequence, eLBC will
issue a command complete interrupt (LTESR[CC]) if interrupts are enabled. Once the sequence has
completed, the shared buffer (buffer 1 for page index 5) and transfer error registers (LTECCR that reports
the 512 blocks with unibit /multibit errors if any) are valid.
13.5.4.5
An example of configuring FCM to execute a block erase command to large-page NAND Flash is shown
in
erase status in MDR[AS0]. The sequence is initiated by writing FMR[OP] = 11, and issuing a special
