EFM32-giant-gecko Timer 6

I’m having the issue where I have CC0 configured as an input capture pin. I have (overflow) OF set to 9ms based on the Timer6 configured peripheral clock (i.e. HFPERCLK, prescaled by 8). When TIMER6->CNT seems to reach the TIMER6->TOP register. All the TIMER6 registers seem to get reset and I have hit the ISR’s overflow.

I can’t find an errata related to this, only one for quadrature operating mode, and that’s not what I have the timer configured for.
