Each PIC16CXXX 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 PIC16CXXX instruc-
tion set summary in Table 13-2 lists byte-oriented, bit-
oriented,
Table 13-1 shows the 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
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.

Preliminary
TABLE 13-1:
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 13-2 lists the instructions recognized by the
MPASM
Figure 13-1 shows the general formats that the instruc-
tions can have.
All examples use the format ‘0xnn’ to represent a
hexadecimal number.

Don’t care location (= 0 or 1).
The assembler will generate code with x = 0.
It is the recommended form of use for com-
patibility 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.
