None
If bit ‘b’ in register ‘f’ is ‘0’, then the
next instruction is skipped.
If bit ‘b’ is ‘0’, then the next
instruction fetched during the current
instruction execution is discarded
and a NOP is executed instead,
making this a two-cycle instruction. 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).
