INDIRECT ADDRESSING
OPERATION
The indirect addressing capability has been enhanced
over that of the PIC16CXX family. There are two control
bits associated with each FSR register. These two bits
configure the FSR register to:
Auto-decrement the value (address) in the FSR
after an indirect access
Auto-increment the value (address) in the FSR
after an indirect access
No change to the value (address) in the FSR after
an indirect access
These control bits are located in the ALUSTA register.
The FSR1 register is controlled by the FS3:FS2 bits
and FSR0 is controlled by the FS1:FS0 bits.
When using the auto-increment or auto-decrement fea-
tures, the effect on the FSR is not reflected in the
ALUSTA register. For example, if the indirect address
causes the FSR to equal '0', the Z bit will not be set.
If the FSR register contains a value of 0h, an indirect
read will read 0h (Zero bit is set) while an indirect write
will be equivalent to a NOP (status bits are not affected).
Indirect addressing allows single cycle data transfers
within the entire data space. This is possible with the
use of the MOVPF and MOVFP instructions, where either
'p' or 'f' is specified as INDF0 (or INDF1).
If the source or destination of the indirect address is in
banked memory, the location accessed will be deter-
mined by the value in the BSR.
A simple program to clear RAM from 20h - FFh is
shown in Example 7-1.

INDIRECT ADDRESSING
7.5
Table Pointer (TBLPTRL and
TBLPTRH)
File registers TBLPTRL and TBLPTRH form a 16-bit
pointer to address the 64K program memory space.
The table pointer is used by instructions TABLWT and
TABLRD
.
The TABLRD and the TABLWT instructions allow trans-
fer of data between program and data space. The table
pointer serves as the 16-bit address of the data word
within the program memory. For a more complete
description of these registers and the operation of
Table Reads and Table Writes, see Section 8.0.
7.6
Table Latch (TBLATH, TBLATL)
The table latch (TBLAT) is a 16-bit register, with
TBLATH and TBLATL referring to the high and low
bytes of the register. It is not mapped into data or pro-
gram memory. The table latch is used as a temporary
holding latch during data transfer between program
and data memory (see TABLRD, TABLWT, TLRD and
TLWT
instruction descriptions). For a more complete
description of these registers and the operation of
Table Reads and Table Writes, see Section 8.0.
