Test f, Skip if 0

0  f  255
a  [0,1]
skip if f = 0
None
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. If ‘a’
is ‘0’, the Access Bank will be selected,
overriding the BSR value. If ‘a’ is ‘1’,
then the bank will be selected as per
the BSR value.
