FIGURE 6-9:  
COMPARING ADDRESSING OPTIONS FOR BIT-ORIENTED AND  
BYTE-ORIENTED INSTRUCTIONS (EXTENDED INSTRUCTION SET ENABLED)  
Example Instruction: ADDWF, f, d, a (Opcode: 0010 01da ffff ffff)  
000h  
When ‘a’ = 0 and f 60h:  
060h  
080h  
The instruction executes in  
Direct Forced mode. ‘f’ is inter-  
Bank 0  
preted as a location in the  
Access RAM between 060h  
and 0FFh. This is the same as  
locations 060h to 07Fh  
(Bank 0) and F80h to FFFh  
(Bank 15) of data memory.

Locations below 60h are not  
available in this addressing  
mode.

Data Memory  
When ‘a’ = 0 and f 5Fh:  
000h  
080h  
100h  
Bank 0  
The instruction executes in  
Indexed Literal Offset mode. ‘f’  
is interpreted as an offset to the  
address value in FSR2. The  
two are added together to  
obtain the address of the target  
register for the instruction. The  
address can be anywhere in  
the data memory space.

Note that in this mode, the  
correct syntax is now:

where ‘k’ is the same as ‘f’.

When ‘a’ = 1 (all values of f):  
Bank 0  
The instruction executes in  
Direct mode (also known as  
Direct Long mode). ‘f’ is inter-  
preted as a location in one of  
the 16 banks of the data  
memory space. The bank is  
designated by the Bank Select  
Register (BSR). The address  
can be in any implemented  
bank in the data memory  
space.
