skip if f = 0
None
If ’f’ = 0, the next instruction,
fetched during the current instruc-
tion execution, is discarded and a
NOP is executed, making this a two-
cycle instruction. If ’a’ is 0, the
Access Bank will be selected, over-
riding the BSR value. If ’a’ is 1,
then the bank will be selected as
per the BSR value (default).
