3. RA = Address of the memory location to be read.
4. RD = Data read from location RA during read operation.
P/N:PM0641
* Refer to Table 4, Figure 12.
** Only the top and the bottom sectors have protect- bit feature. SA = (A20,A19,A18,A17,A16) = 00000B or 11111B is valid.
PD = Data to be programmed at location PA. Data is latched on the rising edge of WE.
SRD = Data read from status register.
5555H and 2AAAH address command codes stand for Hex number starting from A0 to A14.
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 -- A20 will uniquely select any sector.
