Notes:

Instructions shown in grey are obsolete and Microchip recommends that they not be used in order to maintain compatibility with future PIC versions.
Instructions that have a "--------" under the Processor Core column are not valid instructions for that core.
Descriptions shown under the "Operation" column are intended to describe briefly the corresponding instruction's function. In some cases the operation of an instruction varies from family to family. Consult the specific PIC processor's data sheet for more information.
Some instructions shown above perform operations on status and other control flags which are device specific. Consult the specific PIC processor's data sheet for more information.
