13.3.1.22 Flash Byte Count Register (FBCR)
The local bus Flash byte count register (FBCR), shown in
transfers for reads and writes to the NAND Flash EEPROM.
Table 13-30
13.3.1.23 Flash ECC Block n Register (FECC0–FECC3)
The local bus flash ECC blockn register (FECCn), shown in
calculated during writes or reads by eLBC. It can be used for verify after write feature in software. Note
that the valid bit sets before the command completion event and hence the correct ECC could be read
before actual completion of writes/reads.

Byte count determines how many bytes are transferred by the FCM during data read (RB) or data write
(WB) opcodes.
The first byte accessed in the NAND Flash EEPROM is located by the FPAR register, and successive
bytes are transferred until either BC bytes have been counted, or the end of the spare region of the
currently addressed Flash page has been reached.
If BC = 0, an entire Flash page and its spare region will be transferred by FCM, in which case
FPAR[MS] and FPAR[CI] are treated as zero regardless of their values. BC = 0 is the only setting that
permits FCM to generate and check ECC.
