Note : Segment ROM S1, S0 is programed just while 5 LSBs of ADDR are all 0.
Programming for security mode :
When programming in security mode, the waveform is just like above. The programming data is as below :
B11 ~ B1
B0
User defined
Security bit
Note : When security = 0, enable security;
When security = 1, disable security.
