5.9
The procedure for reading configuration memory is
similar to the procedure for reading code memory,
except that 16-bit data words are read (with the upper
byte read being all ‘0’s) instead of 24-bit words. Since
there are twelve Configuration registers, they are read
one register at a time.

Step 1: Exit the 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 0x784) and clock out the
Step 4: Repeat step 3 twelve times to read all the Configuration registers.
Step 5: Reset device internal PC.

TBLPAG register is hard coded to 0xF8 (the upper byte
address of configuration memory) and the read pointer,
W6, is initialized to 0x0000.
