Address bits A

= X = “H” or “L” for all address commands except for Program Address (PA) and Sector
Address (SA).
Bus operations are defined in Table 2.
Both Read/Reset commands are functionally equivalent, resetting the device to the read mode.
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

will
uniquely select any sector.
RD =Data read from location RA during read operation.
PD =Data to be programmed at location PA.
SPA =Sector address to be protected. Set sector address (SA) and (A

) = (0, 1, 0).
SD =Sector protection verify data. Output 01H at protected sector addresses and output 00H at unprotected
sector addresses.
Note:
This command is valid while Fast Mode.
