PIC16F627A/628A/648A
15.0
INSTRUCTION SET SUMMARY
Each PIC16F627A/628A/648A 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
PIC16F627A/628A/648A instruction set summary in
Table 15-2 lists byte-oriented, bit-oriented, and
literal and control
operations. Table 15-1 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.
15.1
Read-Modify-Write Operations
Any instruction that specifies a file register as part of
the instruction performs a Read-Modify-Write (R-M-W)
operation. The register is read, the data is modified,
and the result is stored according to either the instruc-
tion, or the destination designator ‘d’. A read operation
is performed on a register even if the instruction writes
to that register.
For example, a “clrf PORTB” instruction will read
PORTB, clear all the data bits, then write the result
back to PORTB. This example would have the unin-
tended result that the condition that sets the RBIF flag
would be cleared for pins configured as inputs and
using the PORTB interrupt-on-change feature.
TABLE 15-1:
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
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
μs. If a
conditional test is true or the program counter is
changed as a result of an instruction, the instruction
execution time is 2
μs.
Table 15-2 lists the instructions recognized by the
MPASM assembler.
Figure 15-1 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.
FIGURE 15-1:
GENERAL FORMAT FOR
INSTRUCTIONS
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
TO
Time-out bit
PD
Power-down bit
Note 1:
Any unused opcode is reserved. Use of
any reserved opcode may cause unex-
pected operation.
2:
To maintain upward compatibility with
future PIC MCU products, do not use the
OPTION
and TRIS instructions.
Byte-oriented file register operations
d = 0 for destination W
OPCODE
d
f (FILE #)
d = 1 for destination f
f = 7-bit file register address
Bit-oriented file register operations
OPCODE
b (BIT #)
f (FILE #)
b = 3-bit bit address
f = 7-bit file register address
Literal and control operations
OPCODE
k (literal)
k = 8-bit immediate value
OPCODE
k (literal)
k = 11-bit immediate value

CALL
