Enhanced Local Bus Controller
conclusion of the sequence, eLBC will issue a command complete interrupt (LTESR[CC]) if interrupts are
enabled. MDR[AS3–AS0] then can be read to obtain the first 4 bytes of NAND Flash ID.
10.5.3.4
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.
