Flash and Extra Row Programming Procedure
Hardware Security Byte
The following procedure is used to program the Hardware
Security
Byte space
and is summarized in Figure 23:
Set FPS and map Hardware byte (FCON = 0x0C)
Save and disable the interrupts.
Load DPTR at address 0000h.
Load Accumulator register with the data to load.
Execute the MOVX @DPTR, A instruction.
Launch the programming by writing the data sequence 54h followed by A4h in
FCON register. This step of the procedure must be executed from FM1. The end of
the programming indicated by the FBUSY flag cleared.
The end of the programming indicated by the FBusy flag cleared.
Restore the interrupts.
