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.

Step 1: Exit Reset vector.
Step 2: Initialize TBLPAG, the Read Pointer (W6) and the Write Pointer (W7) for TBLRD instruction.
Step 3: Read the Configuration register and write it to the VISI register (located at 784h), and clock out the
Step 4: Repeat Step 3 to read other fuses. Load W6 with their respective address.
Step 5: Reset device internal PC.
