Having difficulty understanding how to change pins in msp432P401 example code ta1_16.c.
I am able to change frequency and duty cycle. Unable to figure out how to change output pins.
Believe it is done via these three lines
P7->Dir |= BIT6 | BIT7;
P7->SEL0 |= BIT6 | BIT7;
P7->SEL1 &|= ( BIT6 | BIT7);
which sets output to p7.6~7 set Ta1.1~2
trying to use pin 2.7
but fails to generate signal after these changes
P2->Dir |= BIT6 | BIT7;
P2->SEL0 |= BIT6 | BIT7;
P2->SEL1 &|= ( BIT6 | BIT7);
Thanks for all the help

Hi Paul,
I believe your issue is because TA1 cannot output to P2.7. Looking at section 6.12 of MSP432P401R, MSP432P401M Mixed-Signal Microcontrollers you can see that P2.6 and P2.7 can be setup to output TA0.3 and TA0.4 respectively:
Whereas, P7.6 and P7.7 can output TA1.2 and TA1.1 respectively:
So it looks like you're trying to output to a pin that the TA1 can't output to. Section 6.9.3 of the above linked document shows which pins are conneted to which timerA outputs.
Best regards,
