1. Type definition: W = Write, R = Read, X can be VIL or VIH, but no other value.
2. Addr (Address) definition: SA = Sector Address = A18-A8, sector size = 256 Bytes; A7-A0 = X for this command.
3. Addr (Address) definition: PA = Program Address = A18-A0.
4. Data definition: PD = Program Data, H = number in hex.
5. SDP = Software Data Protect mode using 7 Read Cycle Sequence.
a) Y = the operation can be executed with protection enabled
b) N = the operation cannot be executed with protection enabled
6. The Chip-Erase function is not supported on industrial temperature 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.
