operation to the bank. At the conclusion of the sequence, eLBC will issue a command complete interrupt
(LTESR[CC]) if interrupts are enabled.
Note that operations specified by OP3 and OP4 (status read) should never be skipped while erasing a
NAND Flash device, because, in case that happens, contention may arise on LGPL4. A possible case is
that the next transaction from eLBC may try to use that pin as an output and since the NAND Flash device
might already be driving it, contention will occur. In case OP3 and OP4 operations are skipped, it may also
happen that a new command is issued to the NAND Flash device even when the device has not yet finished
processing the previous request. This may also result in unpredictable behavior.

An example of configuring FCM to execute a program command to large-page NAND Flash is shown in
Table
RAM, generating ECC as it proceeds. The shared buffer (buffer 1 for page index 5) must be initialized by
software prior to starting the sequence. The sequence is initiated by writing FMR[OP] = 11, and issuing a
special operation to the bank. At the conclusion of the sequence, eLBC will issue a command complete
interrupt (LTESR[CC]) if interrupts are enabled. The status of the programming operation is returned in
MDR[AS0].
Note that operations specified by OP5 and OP6 (status read) should never be skipped while programming
a NAND Flash device, because, in case that happens, contention may arise on LGPL4. A possible case is
that the next transaction from eLBC may try to use that pin as an output and since the NAND Flash device
might already be driving it, contention will occur. In case OP5 and OP6 operations are skipped, it may also
happen that a new command is issued to the NAND Flash device even when the device has not yet finished
processing the previous request. This may also result in unpredictable behavior.
