LAUNCHXL-F28377S: EPWM not working in TB_COUNT_UP mode

Part Number: LAUNCHXL-F28377S

Hello TI community,

I am currently working with the epwm_deadband_cpu01.c program example from controlSuite. I noticed that when I set the CTRMODE to UP count mode, my oscilloscope produced a DC like signal. I was wondering if there is something else that I need to configure to get UP count mode to work as I can only use TB_COUNT_UPDOWN mode right now which limits my desired TBPRD values to be really small.
