PIC32MX210F016D interrupts

The 64 interrupt sources (IRQs) of the interrupt controller (EVIC). IRQ n has its flag in IFSx and its enable bit in IECx, bit n mod 32 of register n ÷ 32; each source jumps to its vector, and some share one: on this chip several IRQs (a UART's receive, transmit and error) use the same vector, so its handler checks their flags. With multi-vector mode on (INTCONbits.MVEC = 1) each vector has its own handler; in XC32 it is void __ISR(_TIMER_1_VECTOR, IPL4AUTO) Timer1Handler(void), its IPL matching the priority set in IPCx.
