Figure 23. Hardware Programming Procedure
Reading the Flash Spaces
User
The following procedure is used to read the User space:
Read one byte in Accumulator by executing MOVC A,@A+DPTR where A+DPTR is
the address of the code byte to read.
Note:
FCON is supposed to be reset when not needed.
Extra Row
The following procedure is used to read the Extra Row space and is summarized in
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.
Hardware Security Byte
The following procedure is used to read the Hardware Security space and is
summarized in Figure 24:
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.
