❐ FA[#] indicates the lowest bit of sector-selected address, i.e.
FA[16] when the large sector is selected (FA[n]=1), and
FA[13] when the small sector is selected (FA[n]=0).
❐ Even Sector indicates an even-number-th sector (large sec-
tor FA[16]=0 / small sector FA[13]=0). Odd Sector indicates
an odd-number-th sector (larget sector FA[16]=1 / small sec-
tor FA[13]=1) "even-number-th" and "odd-number-th" re-
spectively indicate the even number and odd number in
Sector No. values shown in Memory Map.
Input Data Table
In 8 bit program mode, the data of the different input pins based
on the FA[0] values is programmed as shown in Table 73.
When ECCA=1 is input at the program data input, the data is
written to ECC parity bit as well as Regular bit. When ECCA=0
is input at the program data input, the data is written only to Reg-
ular bit. In this case, EDIN[6:0] input value is "don’t care," and re-
gardless of the value, no value is written to ECC parity bit. In the
case of erase operation, regardless of input values to ECCA,
both Regular bit and ECC parity bit are erased together.
