dsPIC30F Flash Programming Specification
11.7
Writing Configuration Memory
The FOSC, FWDT, FBORPOR and FICD registers are
not erasable. It is recommended that all Configuration
registers be set to a default value after erasing program
memory. The FWDT, FBORPOR and FICD registers
can be set to a default all ‘1’s value by programming
0xFFFF to each register. Since these registers contain
unimplemented bits that read as ‘0’ the default values
shown in Table 11-6 will be read instead of 0xFFFF.
The recommended default FOSC value is 0xC100,
which selects the FRC clock oscillator setting.
The FGS, FBS and FSS Configuration registers are
special since they enable code protection for the
device. For security purposes, once any bit in these
registers is programmed to ‘0’ (to enable some code
protection feature), it can only be set back to ‘1’ by
performing a Bulk Erase or Segment Erase as
described
in
Memory in Normal-Voltage Systems”. Programming
these bits from a ‘0’ to ‘1’ is not possible, but they may
be programmed from a ‘1’ to a ‘0’ to enable code
protection.
Table 11-7 shows the ICSP programming details for
clearing the Configuration registers. In Step 1, the
Reset vector is exited. In Step 2, the write pointer (W7)
is loaded with 0x0000, which is the original destination
address (in TBLPAG 0xF8 of program memory). In
Step 3, the NVMCON is set to program one Configura-
tion register. In Step 4, the TBLPAG register is
initialized, to 0xF8, for writing to the Configuration
registers. In Step 5, the value to write to the each
Configuration register (0xFFFF) is loaded to W6. In
Step 6, the Configuration register data is written to the
write latch using the TBLWTL instruction. In Steps 7 and
8, the NVMCON is unlocked for programming and the
programming cycle is initiated, as described in
Mode”. In Step 9, the internal PC is set to 0x100 as a
safety measure to prevent the PC from incrementing
into unimplemented memory. Lastly, Steps 3-9 are
repeated six times until all seven Configuration
registers are cleared.
