(PC)+ 1 TOS,
k  PC<10:0>,
(PCLATH<4:3>)  PC<12:11>
None
Call Subroutine. First, return address
(PC + 1) is pushed onto the stack.
The eleven-bit immediate address is
loaded into PC bits <10:0>. The upper
bits of the PC are loaded from
PCLATH. CALL is a two-cycle instruc-
tion.

None
00h  (W)
1  Z
Z
W register is cleared. Zero bit (Z) is
set.
[ label ] CALLW
(PC) +1  TOS,
(W)  PC<7:0>,
(PCLATH<6:0>) PC<14:8>
Subroutine call with W. First, the
return address (PC + 1) is pushed
onto the return stack. Then, the con-
tents of W is loaded into PC<7:0>,
and the contents of PCLATH into
PC<14:8>. CALLW is a two-cycle
instruction.

The contents of register ‘f’ are com-
plemented. If ‘d’ is ‘0’, the result is
stored in W. If ‘d’ is ‘1’, the result is
stored back in register ‘f’.
Decrement f

result is stored in the W
register. If ‘d’ is ‘1’, the result is stored
back in register ‘f’.

of the WDT.
Status bits TO and PD are set.
