Description:
If bit 'b' in register 鈥檉' 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 鈥榓(ch菐n)鈥� is 0, the
Access Bank will be selected, over-
riding the BSR value. If 鈥榓(ch菐n)鈥� = 1, then
the bank will be selected as per the
