INSTRUCTION SET SUMMARY
Each PIC16F870/871 instruction is a 14-bit word,
divided into an OPCODE, which specifies the instruc-
tion type, and one or more operands, which further
specify
the
operation
of
the
instruction.
The
PIC16F870/871 instruction set summary in Table 12-2
lists byte-oriented, bit-oriented, and literal and con-
trol operations. Table 12-1 shows the opcode field
descriptions.
For byte-oriented instructions, 'f' represents a file reg-
ister designator and 'd' represents a destination desig-
nator. 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 number of 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
eight or eleven bit constant or literal value.
TABLE 12-1:
OPCODE FIELD
DESCRIPTIONS
The instruction set is highly orthogonal and is grouped
into three basic categories:
Byte-oriented operations
Bit-oriented operations
Literal and control operations
All instructions are executed within one single instruc-
tion cycle, unless a conditional test is true, or the pro-
gram counter is changed as a result of an instruction.
In this case, the execution takes two instruction cycles,
with the second cycle executed as a NOP. One instruc-
tion cycle consists of four oscillator periods. Thus, for
an oscillator frequency of 4 MHz, the normal instruction
execution time is 1
s. If a conditional test is true, or the
program counter is changed as a result of an
instruction, the instruction execution time is 2
s.
Table 12-2 lists the instructions recognized by the
MPASMTM assembler.
Figure 12-1 shows the general formats that the
instructions can have.
All examples use the following format to represent a
hexadecimal number:
0xhh
where h signifies a hexadecimal digit.

GENERAL FORMAT FOR
INSTRUCTIONS
A description of each instruction is available in the
PICmicro Mid-Range MCU Family Reference Manual
(DS33023).
Field
Description
f
Register file address (0x00 to 0x7F)
W
Working register (accumulator)
b
Bit address within an 8-bit file register
k
Literal field, constant data or label
x
Don't care location (= 0 or 1).
The assembler will generate code with x = 0.
It is the recommended form of use for
compatibility with all Microchip software tools.
d
Destination select; d = 0: store result in W,
d = 1: store result in file register f.
Default is d = 1.
PC
Program Counter
TO
Time-out bit
PD
Power-down bit
Note:
To maintain upward compatibility with
future PIC16F870/871 products, do not
use the OPTION and TRIS instructions.
