Data Record
Where:
Example:
End of File (EOF), no operation
Where:
Example:
Miscellaneous Write Functions
Where:
Subfunction Code = 01 (Erase Blocks)
Subfunction Code = 04 (Erase Boot Vector and Status Byte)
Subfunction Code = 05 (Program Security Bits)
Subfunction Code = 06 (Program Status Byte or Boot Vector)
NOTE: Only four bits of these Special Cells may be programmed at one time.

ff = 01
ss = block number in bits 7:5, Bits 4:0 = zeros
block 0 : ss = 00h
block 1 : ss = 20h
block 2 : ss = 40h
block 3 : ss = 80h
block 4 : ss = C0h
Example:
ff = 04
ss = don’t care
dd = don’t care
Example:
ff = 05
ss = 00 program security bit 1
Example:
ff = 06
ss = 00 program status byte
