MSP430FR2355: Cannot Change PWM Freq

Tool/software:

I cannot change the PWM duty cycle and period on my MSP430FR2355 EVM kit. I've tried sample code, I've written my own code, and used code I found online, but I still cannot get it to work. Here is my latest code which outputs a 32.7kHz PWM signal on P1.1. However, changing the CCRO, CCR1, and CCR2 values don't change the period of frequncey, it's always 50% at 32.7kHz. Thame sample code in MSPware is for the MSP430FR243x and while I've adapted that to work in this case, I still cannot control the PWM.

Requirements:

Using SMCLK

Ultimately I want a 40kHz PWM so I will be setting CCRO=24 and CCR1=12
