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

register ’f’

(f) + 1
The contents of register ’f’ are
incremented. If ’d’ is 0, the result is
placed in WREG. 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).
