INSTRUCTION SET SUMMARY
Each PIC16C5X instruction is a 12-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 PIC16C5X instruction set summary in
Table 8-2 groups the instructions into byte-oriented, bit-ori-
ented, and literal and control operations. Table 8-1 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 is used to specify which one of the
32 file registers in that bank is to be used by the instruction.
The destination designator specifies where the result of
the operation is to be placed. If ’d’ is ’0’, the result is
placed in the W register. If ’d’ is ’1’, 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
8 or 9-bit constant or literal value.
TABLE 8-1:
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
Label name
TOS
Top of Stack
PC
Program Counter
WDT
Watchdog Timer Counter
TO
Time-out bit
PD
Power-down bit
dest
Destination, either the W register or the specified
register file location

User defined term (font is courier)
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.
One instruction cycle consists of four oscillator periods.
Thus, for an oscillator frequency of 4 MHz, the normal
instruction execution time would be 1
s. If a condi-
tional test is true or the program counter is changed as
a result of an instruction, the instruction execution time
would be 2
s.
Figure 8-1 shows the three general formats that the
instructions can have. All examples in the figure use
the following format to represent a hexadecimal
number:
0xhhh
where ’h’ signifies a hexadecimal digit.
