*1:This command is valid while Fast Mode.
*2:This command is valid while RESET = V
ID
.
*3:The valid addresses are A
6
to A
0
.
*4:This command is valid while Hi-ROM mode.
Note:1. Address bits = X = “H” or “L” for all address commands except or Program Address (PA) and Sector Address
(SA).
2.Bus operations are defined in Table 2.
3.RA = Address of the memory location to be read.
PA = Address of the memory location to be programmed. Addresses are latched on the falling edge of
the write pulse.
SA = Address of the sector to be erased. The combination of A
21
, A
20
, A
19
, A

, A

,A
16
, and A
15
will uniquely
select any sector.
4.RD = Data read from location RA during read operation.
PD = Data to be programmed at location PA. Data is latched on the falling edge of write pulse.
5.SPA = Sector group address to be protected. Set sector group address (SGA) and (A
6
, A
1
, A
0
) = (0, 1, 0).
SD = Sector group protection verify data. Output 01h at protected sector group addresses and output
00h at unprotected sector group addresses.
6.Both Read/Reset commands are functionally equivalent, resetting the device to the read mode.
