In order to program the eLBC and FCM for executing NAND Flash command sequences, command codes

and pause states should be obtained from the relevant NAND Flash device data sheet and programmed into

FCM configuration registers. This section illustrates some common sequences for large-page,

multi-gigabit NAND Flash EEPROMs; however, details should be verified against manufacturers’

specific programming data.

Throughout these examples it is assumed that one or more banks of eLBC has been configured under FCM

control (BRn[MSEL] = 001), with base address, port size, ECC mode, and timing parameters configured

in accordance with the device’s hardware specifications.

An example of configuring FCM to execute a soft reset command to large-page NAND Flash is shown in

by writing FMR[OP] = 10, 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.

Address state is the calculated address for port size.

OP n : These lanes are read or written during that bus transaction. OP0 is the most-significant byte of a doubleword

— Denotes a byte not driven during that read cycle.

operand and OP7 is the least-significant byte.
