Example 4-1 shows the calling of a subroutine in
page 1 of the program memory. This example assumes
that PCLATH is saved and restored by the interrupt ser-
vice routine (if interrupts are used).
EXAMPLE 4-1:
CALL OF A SUBROUTINE IN
PAGE 1 FROM PAGE 0
ORG 0x500
BSF
PCLATH,3
;Select page 1 (800h-FFFh)
CALL
SUB1_P1
;Call subroutine in
:
;page 1 (800h-FFFh)
:
ORG 0x900
SUB1_P1:
;called subroutine
:
;page 1 (800h-FFFh)
:
RETURN
;return to Call subroutine
;in page 0 (000h-7FFh)

Indirect Addressing, INDF and FSR
Registers
The INDF register is not a physical register. Addressing
the INDF register will cause indirect addressing.
Indirect addressing is possible by using the INDF reg-
ister. Any instruction using the INDF register actually
accesses the register pointed to by the File Select Reg-
ister (FSR). Reading the INDF register itself indirectly
(FSR = '0') will produce 00h. Writing to the INDF regis-
ter indirectly results in a no-operation (although status
bits may be affected). An effective 9-bit address is
obtained by concatenating the 8-bit FSR register and
the IRP bit (STATUS<7>), as shown in Figure 4-10.
A simple program to clear RAM locations 20h-2Fh
using indirect addressing is shown in Example 4-2.
EXAMPLE 4-2:
