INSTRUCTION SET SUMMARY
Each PIC16C55X 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 PIC16C55X instruc-
tion set summary in Table 8-2 lists
bit-oriented
, and
literal and control
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 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.

recommended form of use for compatibility with all
Microchip software tools.

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
conditional test is true or the program counter is
changed as a result of an instruction, the instruction
execution time is 2
