19.0
The PIC18CXXX instruction set adds many enhance-
ments to the previous PICmicro instruction sets, while
maintaining an easy migration from these PICmicro
instruction sets.
Most instructions are a single program memory word
(16-bits), but there are three instructions that require
two program memory locations.
Each single word instruction is a 16-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 instruction set is highly orthogonal and is grouped
into four basic categories:
• Byte-oriented operations
• Bit-oriented operations
• Literal operations
• Control operations
The PIC18CXXX instruction set summary in Table 19-2
lists byte-oriented, bit-oriented, literal and control
operations. Table 19-1 shows the opcode field descrip-
tions.
Most byte-oriented instructions have three operands:
1.
2.
3.
The file register designator 'f' specifies which file regis-
ter is to be used by the instruction.
The destination designator ‘d’ specifies where the
result of the operation is to be placed. If 'd' is zero, the
result is placed in the WREG register. If 'd' is one, the
result is placed in the file register specified in the
instruction.
All bit-oriented instructions have three operands:
1.
2.
3.
The bit field designator 'b' selects the number of the bit
affected by the operation, while the file register desig-
nator 'f' represents the number of the file in which the
bit is located.
The literal instructions may use some of the following
operands:
• A literal value to be loaded into a file register
• The desired FSR register to load the literal value
• No operand required (specified by ‘—’)
(specified by ‘k’)
into (specified by ‘f’)

INSTRUCTION SET SUMMARY
The control instructions may use some of the following
operands:
• A program memory address (specified by ‘n’)
• The mode of the Call or Return instructions
• The mode of the Table Read and Table Write
• No operand required (specified by ‘—’)
All instructions are a single word, except for three dou-
ble word instructions. These three instructions were
made double word instructions so that all the required
information is available in these 32-bits. In the second
word, the 4 MSb’s are 1’s. If this second word is exe-
cuted as an instruction (by itself), it will execute as a
NOP.
All single word instructions are executed in a single
instruction cycle, unless a conditional test is true or the
program counter is changed as a result of the instruc-
tion. In these cases, the execution takes two instruction
cycles, with the additional instruction cycle(s) executed
as a NOP.
The double word instructions execute in two instruction
cycles.
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.
Two word branch instructions (if true) would take 3 s.
Figure 19-1 shows the general formats that the instruc-
tions can have.
All examples use the format ‘nnh’ to represent a
hexadecimal number, where ‘h’ signifies a hexadeci-
mal digit.
The Instruction Set Summary, shown in Table 19-2,
lists the instructions recognized by the Microchip
assembler (MPASM
