4.2.2 Mnemonic

Mnemonics tell the assembler which machine instructions to assemble. For example, addition (ADD), branches (BRA) or moves (MOV). Unlike labels that you create yourself, mnemonics are provided by the assembly language. Mnemonics are not case sensitive.

See the dsPIC33A/PIC32A Programmer's Reference Manual (DS-70005540) for more details.
