Program Counter
As a program instruction is executed, the Program
Counter (PC) will contain the address of the next pro-
gram instruction to be executed. The PC value is
increased by one, every instruction cycle, unless an
instruction changes the PC.
For a
GOTO
instruction, bits 8:0 of the PC are provided
by the
GOTO
instruction word. The PC Latch (PCL) is
mapped to PC<7:0> (Figure 4-7 and Figure 4-8).
For
PIC16CR57, PIC16C58 and PIC16CR58, a page num-
ber must be supplied as well. Bit5 and bit6 of the STA-
TUS Register provide page information to bit9 and
bit10 of the PC (Figure 4-8 and Figure 4-9).
the
PIC16C56,
PIC16CR56,
PIC16C57,
For a
CALL
instruction, or any instruction where the
PCL is the destination, bits 7:0 of the PC again are pro-
vided by the instruction word. However, PC<8> does
not come from the instruction word, but is always
cleared (Figure 4-7 and Figure 4-8).
Instructions where the PCL is the destination, or Modify
PCL instructions, include
MOVWF PC, ADDWF PC,
and
BSF PC,5.
For
PIC16CR57, PIC16C58 and PIC16CR58, a page num-
ber again must be supplied. Bit5 and bit6 of the STA-
TUS Register provide page information to bit9 and
bit10 of the PC (Figure 4-8 and Figure 4-9).
the
PIC16C56,
PIC16CR56,
PIC16C57,
Note:
Because PC<8> is cleared in the
CALL
instruction, or any Modify PCL instruction,
all subroutine calls or computed jumps are
limited to the first 256 locations of any pro-
gram memory page (512 words long).
