Notes:
1.Address bit A15 -- A18 = X = Don't care for all address commands except for Program Address(PA) and Sector Address(SA).
5555H and 2AAAH address command codes stand for Hex number starting from A0 to A14.
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 WE pulse.
SA = Address of the sector to be erased. The combination of A16 -- A18 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 rising edge of WE.
SRD = Data read from status register.
5. Only Q0-Q7 command data is taken, Q8-Q15 = Don't care.
* Refer to Table 4, Figure 12.
** Only the top and the bottom sectors have protect- bit feature. SA = (A18,A17,A16) = 000B or 111B is valid.
