INSTRUCTION SET SUMMARY
Each PIC12C5XX 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 PIC12C5XX
instruction set summary in Table 9-2 groups the
instructions into byte-oriented, bit-oriented, and literal
and control operations. Table 9-1 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 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.

Register file address (0x00 to 0x7F)
Working register (accumulator)
Bit address within an 8-bit file register
Literal field, constant data or label
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.
Destination select;
d = 0 (store result in W)
d = 1 (store result in file register ’f’)
Default is d = 1

User defined term (font is courier)
All instructions are executed within a 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. 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.
Figure 9-1 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.
