Data from file register ’f’ is written into
the 16-bit table latch (TBLAT).
If t = 1; high byte is written
If t = 0; low byte is written
This instruction is used in conjunction
with TABLWT to transfer data from data
memory to program memory.

If ’f’ = 0, the next instruction, fetched
during the current instruction execution,
is discarded and a NOP is executed,
making this a two-cycle instruction.
