ECCDecDone
[6]
When 4-bit ECC or 8-bit ECC decoding is finished, this value set
and issue interrupt if enabled. The NFMLCBITPT, NFMLCL0 and
NFMLCEL1 have valid values. To clear this, write ‘1’.
1 = 4-bit ECC or 8-bit ECC decoding is completed
0
IllegalAccess
[5]
Once Soft Lock or Lock-tight is enabled, The illegal access
(program, erase) to the memory makes this bit set.
0 = Illegal access is not detected
1 = Illegal access is detected
0
RnB_TransDetect
[4]
When RnB low to high transition is occurred, this value set and
issue interrupt if enabled. To clear this write ‘1’.
0 = RnB transition is not detected
1 = RnB transition is detected
Transition configuration is set in RnB_TransMode(NFCONT[8]).
1
NCE[1]
(Read-only)
[3]
The status of nRCS[1] output pin
1
NCE[0]
(Read-only)
[2]
The status of nFCE output pin
1
Reserved [1]
Reserved
0
RnB
(Read-only)
[0]
The status of RnB input pin.
0 = NAND Flash memory busy
1 = NAND Flash memory ready to operate
