3.5.6 Interrupt Priority Programmable Register (INPPRn)
The INPPR registers enable interrupt priority to be programmed. Default interrupt priority is changed by setting the
INPPR registers. INTMOD[31] bit controls the priority program capability. Software must set the INTMOD[31] bit to ‘1’
before programming the INPPR registers. Setting the INTMOD[31] bit to ‘0’ immediately reverts the interrupt priority back
to the default configuration.
