GOTO allows an unconditional
branch anywhere within entire
2 Mbyte memory range. The 20-bit
value ’k’ is loaded into PC<20:1>.
GOTO is always a two-cycle
instruction.

(f) + 1
The contents of register ’f’ are
incremented. If ’d’ is 0, the result is
placed in W. If ’d’ is 1, the result is
placed back in register ’f’ (default).
If ’a’ is 0, the Access Bank will be
selected, overriding the BSR value.
If ’a’ = 1, then the bank will be
selected as per the BSR value
(default).
