PIC10F200/202/204/206  
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 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.  
10.0 INSTRUCTION SET SUMMARY  
The PIC16 instruction set is highly orthogonal and is  
comprised of three basic categories.  
Byte-oriented operations  
Bit-oriented operations  
Literal and control operations  
Each PIC16 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 formats for each of the categories  
is presented in Figure 10-1, while the various opcode  
fields are summarized in Table 10-1.  
Figure 10-1 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  
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.  
where ‘h’ signifies a hexadecimal digit.  
FIGURE 10-1:  
GENERAL FORMAT FOR  
INSTRUCTIONS  
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.

f (FILE #)  
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.  
d = 0for destination W  
d = 1for destination f
