INSTRUCTION SET SUMMARY
Each PIC16CE62X 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 PIC16CE62X instruc-
tion set summary 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
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 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.
TABLE 11-1:
OPCODE FIELD
DESCRIPTIONS
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

Label name

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
instruction cycle, unless a conditional test is true or the
program 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 instruction 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 11-1 lists the instructions recognized by the
MPASM assembler.
Figure 11-1 shows the three 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.

To maintain upward compatibility with
future PICmicro products, do not use the

and TRIS instructions.
