placed in WREG. If 'd' is 1 the result is
placed in register 'f'.

A byte of the table latch (TBLAT)
is moved to register file 'f'.
If t = 0: the high byte is moved;
If t = 1: the low byte is moved
Then the contents of the program
memory location pointed to by
the
(TBLPTR) is loaded into the
16-bit Table Latch (TBLAT).
If i = 1: TBLPTR is incremented;
If i = 0: TBLPTR is not
