Call Subroutine
[ label ] CALL k

(PC)+ 1
k
(PCLATH<4:3>)
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
instruction.

Z
The contents of register ‘f’ are
complemented. If ‘d’ is ‘0’, the
result is stored in W. If ‘d’ is ‘1’,
the result is stored back in
register ‘f’.
Decrement f
[ label ] DECF f,d
0
d
(f) – 1
Z
Decrement register ‘f’. If ‘d’ is ‘0’,
the result is stored in the W
register. If ‘d’ is ‘0’, the result is
stored back in register ‘f’.
