I am using MSP430FR2110 and trying to setup a pin interrupt on P1.6. The code is avaiable below.
I am having an issue where pin interrupt is not generated when voltage level transition from high to low on pin P1.6.
I happen to have a dev kit with MSP430FR2311. With the same code, pin interrupt works. I can't find anything saying that
MSP430FR2110 P1.6 cannot be use as pin interrupt from the datasheets.
Can someone help me?
// #include <msp430.h>
// int main(void)
// {
// WDTCTL = WDTPW | WDTHOLD; // Stop watchdog timer
// P1OUT |= BIT6; // Configure P1.6 as pulled-up
// P1REN |= BIT6; // P1.6 pull-up register enable
// P1IES |= BIT6; // P1.6 Hi/Low edge
// P1IE |= BIT6; // P1.6 interrupt enabled
// // Disable the GPIO power-on default high-impedance mode
// // to activate previously configured port settings
// PM5CTL0 &= ~LOCKLPM5;
// P1IFG &= ~BIT6; // P1.6 IFG cleared
// while(1)
// {
// __bis_SR_register(GIE); // Enter LPM3 w/interrupt
// __no_operation(); // For debug
// }
// }
// // Port 1 interrupt service routine
// #if defined(__TI_COMPILER_VERSION__) || defined(__IAR_SYSTEMS_ICC__)
// #pragma vector=PORT1_VECTOR
// __interrupt void Port_1(void)
// #elif defined(__GNUC__)
// void __attribute__ ((interrupt(PORT1_VECTOR))) Port_1 (void)
// #else
// #error Compiler not supported!
// #endif
// {
// P1IFG &= ~BIT6; // Clear P1.6 IFG
// }
