PICmicro MID-RANGE MCU FAMILY
29.1
DS31029A-page 29-2
Introduction
Each midrange instruction is a 14-bit word divided into an OPCODE which specifies the instruc-
tion type and one or more operands which further specify the operation of the instruction. The
midrange Instruction Set Summary in
assembler. The instruction set is highly orthogonal and is grouped into three basic categories:
• Byte-oriented operations
• Bit-oriented operations
• Literal and control operations
Table 29-2
For byte-oriented instructions, 'f' represents a file register designator and 'd' represents a des-
tination 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.
All instructions are executed in one single instruction cycle, unless a conditional test is true or the
program counter is changed as a result of an instruction. In these cases, the execution takes two
instruction cycles with the second cycle executed as an NOP. One instruction cycle consists of
four oscillator periods. Thus, for an oscillator frequency of 4 MHz, the normal instruction execu-
tion 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.
