Enhanced Local Bus Controller
512 bytes appear as main region data, and 16 bytes appear as spare region data. The EEPROM’s page
numbered P is associated with buffer number (P mod 8), where P = FPAR[PI]. Since the bank size set by
ORn[AM] will be greater than 8 Kbytes, an identical image of the FCM buffer RAM appears replicated
every 8 Kbytes throughout the bank address space. It is recommended that the bank size be set to 32
Kbytes, which covers a single NAND Flash block for small-page devices.
For FCM commands, register FPAR sets the page address and, therefore, also the buffer number.In the case
that FBCR[BC] = 0, FCM transfers an entire page, comprising the 512-byte main region followed by the
16-byte spare region; the 496-byte reserved region is not accessed, and remains undefined for software.
However, for commands given a specific byte count in FBCR[BC], FPAR[MS] locates the starting address
in either the main region (MS = 0) or the spare region (MS = 1). Where different eLBC banks control both
small and large-page devices, a large-page 4-Kbyte buffer must be assigned to either the first 4 or last 4
small-page buffers.

The FCM buffer space is divided into two 4 Kbyte buffers for large-page devices (ORn[PGS] = 1), mapped
as shown in
appear as main region data, and 64 bytes appear as spare region data. The EEPROM’s page numbered P
is associated with buffer number (P mod 2), where P = FPAR[PI]. Since the bank size set by ORn[AM]
will be greater than 8 Kbytes, an identical image of the FCM buffer RAM appears replicated every 8
Kbytes throughout the bank address space. It is recommended that the bank size be set to 256 Kbytes,
which covers a single NAND Flash block for large-page devices.
For FCM commands, register FPAR sets the page address and, therefore, also the buffer number. In the
case that FBCR[BC] = 0, FCM transfers an entire page, comprising the 2048-byte main region followed
by the 64-byte spare region; the 1984-byte reserved region is not accessed, and remains undefined for
