INSTRUCTION SET SUMMARY
Each PIC16C62X(A) instruction is a 14-bit word
divided into an OPCODE which specifies the instruc-
tion type and one or more operands which further spec-
ify the operation of the instruction. The PIC16C62X(A)
instruction set summary in Table 10-2 lists
byte-ori-
ented
,
bit-oriented
, and
literal and control
opera-
tions. Table 10-1 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.

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

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
μ
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
μ
s.
Table 10-1 lists the instructions recognized by the
MPASM assembler.
Figure 10-1 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.
