#include <msp430.h>
void main(void) {WDTCTL = WDTPW | WDTHOLD;// Stop watchdog timerPM5CTL0 &= ~LOCKLPM5;// Disable the GPIO power-on default high-impedance mode// to activate previously configured port settingsP1DIR = 0x01;// Set P1.0 to output directionP1OUT = 0x00;P1REN = 0x00;while(1){if ((P1IN & 0x08) == 0x08)P1OUT = 0x01;elseP1OUT = 0x00;}
}
In this code, i am try to achieve a voltage detecttion, however, i don't know the meaning of code "PM5CTL0 &= ~LOCKLPM5;". if i delete it, the output of specific pin would keep in off state.
So i want to the accurate meaning of the code "PM5CTL0 &= ~LOCKLPM5;" and how to use it correctly.
