The PIC32MX3XX/4XX family instruction set complies
with the MIPS32 Release 2 instruction set architecture.
PIC32MX does not support the following features:

• CoreExtend instructions 

• Coprocessor 1 instructions

• Coprocessor 2 instructions

 provides a summary of the instructions that

are implemented by the PIC32MX3XX/4XX family
core.
