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.
