INSTRUCTION SET SUMMARY
Each PIC16CXXX instruction is a 14-bit word divided
into an OPCODE which species the instruction type
and one or more operands which further specify the
operation of the instruction. The PIC16CXX instruction
set summary in Table 15-2 lists byte-oriented, bit-ori-
ented, and literal and control operations. Table 15-1
shows the opcode eld descriptions.
For byte-oriented instructions, 'f' represents a le reg-
ister designator and 'd' represents a destination desig-
nator. The le register designator species which le
register is to be used by the instruction.
The destination designator species 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 le register specied in the instruction.
For bit-oriented instructions, 'b' represents a bit eld
designator which selects the number of the bit affected
by the operation, while 'f' represents the number of the
le in which the bit is located.
For literal and control operations, 'k' represents an
eight or eleven bit constant or literal value.
The instruction set is highly orthogonal and is grouped
into three basic categories:
Byte-oriented operations
Bit-oriented operations
Literal and control operations

TABLE 15-1: OPCODE FIELD DESCRIPTIONS
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 instruc-
tion, the instruction execution time is 2
s.
Table 15-2 lists the instructions recognized by the
MPASM assembler.
Figure 15-1 shows the general formats that the instruc-
tions can have.
All examples use the following format to represent a
hexadecimal number:
0xhh
where h signies a hexadecimal digit.
Field
Description
f
Register le address (0x00 to 0x7F)
W
Working register (accumulator)
b
Bit address within an 8-bit le register
k
Literal eld, 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 le register f.
Default is d = 1
