25.3.17 4-Symbol ECC Error Count Register (FL4ECCCNT)
FL4ECCCNT is a 32-bit readable register that indicates the number of errors detected by the 4-
symbol ECC circuit. Only 0 can be written to this register. To clear this register, write 0 to all bits.

These bits are always read as 0. The write value should
always be 0.

H'000 R/W Error Counter
Only 0 can be written to these bits.
Indicates the total number of errors found in a series of
sectors that have been read (for one block at maximum,
which consists of 64 pages 4 sectors).
If a sector contains five or more errors, they are
counted as five.
15 to 3 All 0 R Reserved
These bits are always read as 0. The write value should
always be 0.
