INSTRUCTION SET SUMMARY
The PIC14000’s instruction set is the same as
PIC16CXX. Each 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 instruction set sum-
mary in Table 11-2 lists byte-oriented, bit-oriented, and
literal and control operations. Table 11-1 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 number 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.

The assembler will generate code with x = 0. It is the
recommended form of use for compatibility with all
Microchip software tools.
Destination select; d = 0: store result in W,
d = 1: store result in file register f.
Default is d = 1

talics
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
μ
s. If a conditional test is true or the
program counter is changed as a result of an instruc-
tion, the instruction execution time is 2
Table 11-2 lists the instructions recognized by the
MPASM assembler.
Figure 11-1 shows the three general formats that the
instructions can have.
μ
s.
All examples use the following format to represent a
hexadecimal number:
0xhh
where h signifies a hexadecimal digit.

Note:
To maintain upward compatibility with
future PIC16CXX products, do not use the
OPTION
and
TRIS
instructions.
