(PC)+ 1 TOS,
k PC<10:0>,
(PCLATH<6:3>) PC<14:11>
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
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.

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

Z
Decrement register ‘f’. If ‘d’ is ‘ 0 ’, the
result is stored in the W
register. If ‘d’ is ‘ 1 ’, the result is stored
back in register ‘f’.

CLRWDT instruction resets the Watch-
dog Timer. It also resets the prescaler
of the WDT.
Status bits TO and PD are set.
