-----------------------------------------

PORT_PCR_MUX(1);
GPIO_PDDR_PDD(0x800);

Hi Shruthi_C,

PCC->PCCn[PCC_PORTA_INDEX ]|=PCC_PCCn_CGC_MASK; /* Enable clock for PORTA */
PORTA->PCR[11] = 0x00000100; /* Port A11: MUX = GPIO */
PTA->PDDR |= 1<<11; /* Port A11: Data Direction= output */
PTA->PTOR |= 1<<11; /* toggle output port A11 */

Best Regards,
Robin
