Single Shot Mode of T12, T13 is edge-aligned mode only.
Hysteresis-Like Control Mode
The hysteresis-like control mode (MSEL6x = ’1001’) offers the possibility to switch off the
PWM output if the input CCPOSx becomes ’0’. This can be used as a simple motor
control feature by using a comparator indicating e.g. over current.
