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
Figure 24:
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.
