Read one byte in Accumulator by executing MOVC A,@A+DPTR where A+DPTR is
the address of the code byte to read.
Map the Extra Row space by writing 02h in FCON register.
Read one byte in Accumulator by executing MOVC A,@A+DPTR with A = 0 and
DPTR = FF80h to FFFFh.
Clear FCON to unmap the Extra Row.
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 and
DPTR = 0000h.
Clear FCON to unmap the Hardware Security Byte.
FCON is supposed to be reset when not needed.
