What is Interrupt Exception Processing Vectors and Priorities Table?

Latest Updated:03/25/2009

Question:

I do not understand the interrupts whose interrupt sources are I/O listed in the Interrupt Exception Processing Vectors and Priorities Table in the section of the interrupt controller of the hardware manual.

Answer:

The interrupts whose interrupt sources are I/O (0EI/MTUP0E/MTU0EI) are used in the Port Output Enable function (POE). These interrupts are generated according to the settings of P0E# to P03# pins or the output state of large-current pins. Please refer to "Port Output Enable (POE)" in the section of the multifunction timer pulse unit (MTU) of the hardware manual for details.
