TOV
Toggles the output compare pin on overflow for each channel. This feature only takes effect when in output compare
mode. When set, it takes precedence over forced output compare but not channel 3 override events. These bits are
read anytime, write anytime.
1 Toggle output compare pin on overflow feature enabled
0 Toggle output compare pin on overflow feature disabled
