PIC24FXXKAXXX
3.11
The procedure for reading a Configuration register is
the same as reading the code memory. The only
difference is that the 16-bit data words are read (with
the upper byte read being all ‘0‘s) instead of the 24-bit
words. There are eight Configuration registers and they
are read one register at a time.

Initialize TBLPAG, the Read Pointer (W6) and the Write Pointer (W7) for TBLRD instruction.
Repeat Step 3 to read other fuses. Load W6 with their respective address.
Reset device internal PC.
Reading Configuration Memory
Read the Configuration register and write it to the VISI register (located at 784h), and clock out the
VISI register using the REGOUT command.
