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 two Configuration registers, they are read one
register at a time.

DS39768D-page 24
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 again to read Configuration Word 1.
Step 5: Reset device internal PC.

Table 3-9 shows the ICSP programming details for
reading the Configuration Words. Note that the
TBLPAG register must be loaded with 00h for 96 Kbyte
and below devices and 01h for 128 Kbyte devices (the
upper byte address of configuration memory), and the
Read Pointer, W6, is initialized to the lower 16 bits of
the Configuration Word location.
