Notes:
1: The Power Down Program can be performed one time after compliance of Power-up timings and it should not be
re-programmed after regular Read or Write. Unspecified addresses, A0 to A15, can be either High or Low during
the programming. The RESERVED key should not be used.
2: TOP area is from the lowest address location. (i.e., A[20:0] = H))
3: BOTTOM area is from the highest address location. (i.e., A[20:0] = L)
4: NAP and SLEEP do not retain the data and Area Select is ignored.
5: Default state. Power Down Program to this SLEEP mode can be omitted.
