if Zero bit is ’1’
(PC) + 2 + 2n
None
If the Zero bit is ’1’, then the pro-
gram will branch.
The 2’s complement number ’2n’ is
added to the PC. Since the PC will
have incremented to fetch the next
instruction, the new address will be
PC+2+2n. This instruction is then
a two-cycle instruction.

Subroutine call of entire 2 Mbyte
memory range. First, return
address (PC+ 4) is pushed onto the
return stack. If ’s’ = 1, the W,
STATUS and BSR registers are
also pushed into their respective
shadow registers, WS, STATUSS
and BSRS. If 's' = 0, no update
occurs (default). Then, the 20-bit
value ’k’ is loaded into PC<20:1>.
CALL is a two-cycle instruction.
