Hardware Security
Figure 8-6.
The following procedure is used to program the Hardware Security space and is summarized in
Figure 8-7:
• Set FPS and map Hardware byte (FCON = 0x0C)
• 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
• Enable the interrupts.
