Thank you so much pgo. You are right. I didn't configure the clock for that module.
After configuring, It worked. Now the default handler is not coming and the port is properly configured.
I have one more doubt.
I am using KL05Z microcontroller. When I checked the kinetis_sysinit.c, I could see the interrupt vector table.
/* The Interrupt Vector Table */
void (* const InterruptVector[])() __attribute__ ((section(".vectortable"))) = {
/* Processor exceptions */
(void(*)(void)) &_estack,
__thumb_startup,
NMI_Handler,
HardFault_Handler,

FTM2_IRQHandler, /* FTM2 fault, overflow and channels interrupt */
RTC_Alarm_IRQHandler, /* RTC Alarm interrupt */
RTC_Seconds_IRQHandler, /* RTC Seconds interrupt */
PIT_IRQHandler, /* PIT timer all channels interrupt */
Default_Handler, /* Reserved interrupt 39/23 */
USBOTG_IRQHandler, /* USB interrupt */
DAC0_IRQHandler, /* DAC0 interrupt */
TSI0_IRQHandler, /* TSI0 Interrupt */
MCG_IRQHandler, /* MCG Interrupt */
LPTimer_IRQHandler, /* LPTimer interrupt */
Default_Handler, /* Reserved interrupt 45/29 */
PORTA_IRQHandler, /* Port A interrupt */
PORTD_IRQHandler /* Port D interrupt */
};
Why does this PORD_IRQHandler present here?? This microcontroller doesn't have a PORTD.
And what should I do If I have to create a PORTB_IRQHandler ???
Thanks and regards
