(1) Please confirm the setting of the interrupt priority.
It is necessary to set the interrupt priority corresponding to each interrupt factor according to interrupt priority level set register (IPR). When the priority level of interrupt set here is the same or lower level as the priority level set to interrupt mask level bit (I3~I0), the interrupt is ignored.
(2)Please confirm whether the on-chip peripheral module that is an interrupt factor is set to a module standby.
The initial value of the main on-chip peripheral function is set in the state of the module standby.
In the state of module standby, interrupt is not generated because on-chip peripheral function is not operated.
