11.11 Reading Configuration Memory
The procedure for reading configuration memory is
similar to the procedure for reading code memory,
except that 16-bit data words are read instead of 24-bit
words. Since there are seven Configuration registers,
they are read one register at a time.

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