All of the other pins form a nice square wave from 0V to 3.2V. However, P1.5 ranges from 1.5V to 3.2V. Why is there this offset and how do I get rid of it? Also, any tips on how to paste code formatting to preserve indents to make it more readable?
Thanks!
#include <msp430.h>
int main(void)

WDTCTL = WDTPW | WDTHOLD; // Stop WDT

P1SEL1 |= BIT1 | BIT2 |BIT4 |BIT5; // P1.1 and P1.2 options select
// Disable the GPIO power-on default high-impedance mode to activate
// previously configured port settings
PM5CTL0 &= ~LOCKLPM5;
TA0CCR0 = 300; // PWM Period

TA0CCR1 = 276; // CCR1 PWM duty cycle

TA0CCR2 = 276; // CCR2 PWM duty cycle
TA0CTL = TASSEL__SMCLK | MC__UP | TACLR; // SMCLK, up mode, clear TAR
