INSTRUCTION SET SUMMARY
The PIC12F609/615/12HV609/615 instruction set is
highly orthogonal and is comprised of three basic cate-
gories:
Byte-oriented
operations
Bit-oriented
operations
Literal and control
operations
Each PIC16 instruction is a 14-bit word divided into an
opcode,
which specifies the instruction type and one or
more
operands,
which further specify the operation of
the instruction. The formats for each of the categories
is presented in Figure 13-1, while the various opcode
fields are summarized in Table 13-1.
Table 13-2 lists the instructions recognized by the
MPASM
TM
assembler.
For
byte-oriented
instructions, ‘f’ represents a file
register designator and ‘d’ represents a destination
designator. The file register designator specifies which
file register is to be used by the instruction.
The destination designator specifies where the result of
the operation is to be placed. If ‘d’ is zero, the result is
placed in the W register. If ‘d’ is one, the result is placed
in the file register specified in the instruction.
For
bit-oriented
instructions, ‘b’ represents a bit field
designator, which selects the bit affected by the
operation, while ‘f’ represents the address of the file in
which the bit is located.
For
literal and control
operations, ‘k’ represents an
8-bit or 11-bit constant, or literal value.
One instruction cycle consists of four oscillator periods;
for an oscillator frequency of 4 MHz, this gives a normal
instruction execution time of 1
μ
s. All instructions are
executed within a single instruction cycle, unless a
conditional test is true, or the program counter is
changed as a result of an instruction. When this occurs,
the execution takes two instruction cycles, with the
second cycle executed as a
NOP
.
All instruction examples use the format ‘
0xhh
’ to
represent a hexadecimal number, where ‘
h
’ signifies a
hexadecimal digit.
13.1
Read-Modify-Write Operations
Any instruction that specifies a file register as part of
the instruction performs a Read-Modify-Write (RMW)
operation. The register is read, the data is modified,
and the result is stored according to either the instruc-
tion or the destination designator ‘d’. A read operation
is performed on a register even if the instruction writes
to that register.
For example, a
CLRF GPIO
instruction will read GPIO,
clear all the data bits, then write the result back to
GPIO. This example would have the unintended conse-
quence of clearing the condition that set the GPIF flag.

f

Working register (accumulator)
Bit address within an 8-bit file register
Literal field, constant data or label
Don’t care location (=

The assembler will generate code with x =

.
It is the recommended form of use for
compatibility with all Microchip software tools.
Destination select; d =

: store result in

d =

: store result in file register f.
Default is d =
1.
