TIMER 32-bit on pic32 can't use interrupts - c

Question

Hi I have a PIC32MX370F512L from microchip.
I want to use TIMER2 and TIMER3 as a 32-bit timer for interrupts.
I CAN use 16-bit Timer interrupt but CAN'T use 32-bit Timer interrupt, I will show you both codes:
16-bit timer:
void init16(){
T2CONbits.ON = 0; //Timer disabled
T2CON = 0; //Stop any 16-bit Timer2 operation
T2CONbits.T32 = 0; //16 bit mode on, tmr2
T2CONbits.TCKPS = 0b100; //prescaler
T2CONbits.TCS = 0; //Select internal peripheral clock
PR2 = 0x0000FFFF;
TMR2 = 0; //Clear contents of TMR2
T2CONbits.ON = 1; //Timer enable
//====INTERRUPT PART========
IEC0bits.T2IE = 0; //Disable interrupt
IPC2bits.T2IP = 1; //Priority 1
//IPC3bits.T3IS = 0; //Sub-priority 3
IFS0bits.T2IF = 0; //Interrupt flag putted at zero
//IFS0bits.T3IF = 0; //Interrupt flag putted at zero
IEC0bits.T2IE = 1; //Enable interrupt
}
32-bit timer:
void init32(){
T2CONbits.ON = 0; //Timer disabled
T2CON = 0; //Stop any 16/32-bit Timer2 operation
T3CON = 0; //Stop any 16-bit Timer3 operation
T2CONbits.T32 = 1; //32 bit mode on, tmr2 + tmr3
T2CONbits.TCKPS = 0b100; //Prescaler
T2CONbits.TCS = 0; //Select internal peripheral clock
PR2 = 0x000FFFFF;
//PR3 = 0;
TMR2 = 0; //Clear contents of TMR2 and TMR3
T2CONbits.ON = 1; //Timer enable
//====INTERRUPT PART========
IEC0bits.T3IE = 0; //Disable interrupt
IPC3bits.T3IP = 1; //Priority 1
//IPC3bits.T3IS = 0; //Sub-priority 0
IFS0bits.T3IF = 0; //Interrupt flag putted at zero
//IFS0bits.T3IF = 0; //Interrupt flag putted at zero
IEC0bits.T3IE = 1; //Enable interrupt
}
main :
#include <stdio.h>
#include <stdlib.h>
#include <p32xxxx.h>
#include <plib.h>
#include "timer32Interrupt.h"
#include <xc.h>
/* Disable JTAG to use RA0 */
#pragma config JTAGEN = OFF
#pragma config FWDTEN = OFF //Watchdog disabled
/* Device Config Bits in DEVCFG1: */
#pragma config FNOSC = FRCPLL //Fast RC Osc with PLL
#pragma config FSOSCEN = OFF //Secondary Oscillator disabled
#pragma config POSCMOD = XT //Primary Oscillator mode: Resonator, crystal or resonator
#pragma config OSCIOFNC = ON //CLKO Output Signal Active on the OSCO Pin
#pragma config FPBDIV = DIV_2 //Peripheral Clock Divisor: PBCLK is SYSCLK divided by 2
/* Device Config Bits in DEVCFG2: */
#pragma config FPLLIDIV = DIV_2 //PLL Input Divider
#pragma config FPLLMUL = MUL_20 //PLL Multiplier
#pragma config FPLLODIV = DIV_2 //System PLL Output Clock Divider: PLL Divide by 2
void main(){
TRISA = 0;
LATA = 0;
LATAbits.LATA0 = 1;
//LATAbits.LATA0 =~LATAbits.LATA0
INTEnableSystemMultiVectoredInt();
init32();
//init16();
while(1){
int i = 0;
if(TMR2 >= PR2 - 10 ){
//LATAbits.LATA0 =~LATAbits.LATA0;
//LATAbits.LATA2 =~LATAbits.LATA2;
LATAINV = 0b10;
}
}
}
void __ISR(_TIMER_2_VECTOR, ipl1)Timer32Handler(void){
LATAINV = 0b101;
IFS0bits.T3IF = 0; //Interrupt flag putted at zero
IFS0bits.T2IF = 0; //Interrupt flag putted at zero
}
The 16 bit implementation works and the 32 not, enabling interrupt on TIMER3 and not on TIMER2 is required in the data-sheet, section 14.3.4 of the timers.

Answer 1

Like said by #Sudhee for making the code work I should replace only this part:
_TIMER_2_VECTOR became _TIMER_3_VECTOR
void __ISR(_TIMER_3_VECTOR, ipl1)Timer32Handler(void){
LATAINV = 0b101;
IFS0bits.T3IF = 0; //Interrupt flag putted at zero
IFS0bits.T2IF = 0; //Interrupt flag putted at zero
}
