EXAMPLE 8-8:
8.6.2.2
After completing all useful code of the interrupt handler
routine, the original state of the Status and ErrorEPC
registers, along with the General Purpose Registers
saved on the stack, must be restored. (The Status and
ErrorEPC registers are located in the CPU; refer to
Section 2.0 "PIC32MX MCU" of this manual for more
information.)
