21.0
Each PIC16 instruction is a 14-bit word containing the
operation code (opcode) and all required operands.
The opcodes are broken into three broad categories.
• Byte Oriented
• Bit Oriented
• Literal and Control
The literal and control category contains the most var-
ied instruction word format.
Table 21-3
MPASM
All instructions are executed within a single instruction
cycle, with the following exceptions, which may take
two or three cycles:
• Subroutine takes two cycles (CALL, CALLW)
• Returns from interrupts or subroutines take two
• Program branching takes two cycles (GOTO, BRA,
• One additional instruction cycle will be used when
One instruction cycle consists of 4 oscillator cycles; for
an oscillator frequency of 4 MHz, this gives a nominal
instruction execution rate of 1 MHz.
All instruction examples use the format ‘0xhh’ to
represent a hexadecimal number, where ‘h’ signifies a
hexadecimal digit.

INSTRUCTION SET SUMMARY

lists the instructions recognized by the
Preliminary
21.1
Any instruction that specifies a file register as part of
the instruction performs a Read-Modify-Write (R-M-W)
operation. The register is read, the data is modified,
and the result is stored according to either the instruc-
tion, or the destination designator ‘d’. A read operation
is performed on a register even if the instruction writes
to that register.

The assembler will generate code with x = 0.
It is the recommended form of use for
compatibility with all Microchip software tools.
