Enhanced Local Bus Controller
10.3.1.18 Flash Instruction Register (FIR)
The local bus Flash instruction register (FIR), shown in
instructions for issue by the FCM. Setting FMR[OP] non-zero and writing LSOR or accessing a bank
controlled by FCM causes FCM to read FIR 4 bits at a time, starting at bit 0 and continuing with adjacent
4-bit opcodes, until only NOP opcodes remain. The programmed instruction sequence of OP0, OP1,...,
OP7 is performed on the activated bank, using the data buffer addressed by FPAR. If LTEIR[CCI] = 1 and
LTEDR[CCD] = 0, eLBC will generate an interrupt once the entire sequence has completed, and software
should examine LTEATR and clear its V bit.

Software must not alter the contents of the addressed FCM buffer, FIR, MDR, FCR, FBAR, FPAR, or
FBCR while an operation is in progress—or eLBC will behave unpredictably—but software can freely
modify the contents of any currently unused FCM RAM buffer in preparation for the next operation.

Address length. AL sets the number of address bytes issued during page address (PA) operations.
However, the number of address bytes issued for column address (CA) operations is determined by
the device page size (for OR n [PGS] = 0, 1 CA byte is issued; for OR n [PGS] = 1, 2 CA bytes are issued).
00 2 bytes are issued for page addresses, thus a total of 3 (OR n [PGS] = 0) or 4 (OR n [PGS] = 1)
01 3 bytes are issued for page addresses, thus a total of 4 (OR n [PGS] = 0) or 5 (OR n [PGS] = 1)
10 4 bytes are issued for page addresses, thus a total of 5 (OR n [PGS] = 0) or 6 (OR n [PGS] = 1)

Flash operation. For OP not equal to 00, a special operation is triggered on the next write to LSOR or
dummy access to a bank controlled by FCM. Once a special operation has commenced, OP is
automatically reset to 00 by FCM. Individual blocks may be temporarily unlocked for erase and
reprogramming operations.
