1. X can be V
1. Type definition: W = Write, R = Read, X can be V
2. Addr (Address) definition: SA = Sector Address = A
3. Addr (Address) definition: PA = Program Address = A
4. Data definition: PD = Program Data, H = number in hex.
5. SDP = Software Data Protect mode using 7 Read Cycle Sequence.
6. The Chip-Erase function is not supported on SST28VF040A industrial parts.
7. Address 0000H retrieves the Manufacturer’s ID of BFH and address 0001H retrieves the Device ID of 04H.
8. Refer to Figure 11 for the 7 Read Cycle sequence for Software_Data_Protect.
9. Refer to Figure 10 for the 7 Read Cycle sequence for Software_Data_Unprotect.
a) Y = the operation can be executed with protection enabled
b) N = the operation cannot be executed with protection enabled
