Hardware Security
The following procedure is used to read the Hardware Security space and is summarized in
Figure 8-8:
Figure 8-8.
Table 8-4.
Reset Value = 0000 0000b
• Map the Hardware Security space by writing 04h in FCON register.
• Read the byte in Accumulator by executing MOVC A, @A+DPTR with A = 0 & DPTR =
0000h.
