Decoder
Interruptions can be generated on different events.
A compare function (using TC_RC register) is available on channel 0 (speed/position) or chan-
nel 1 (rotation) and can generate an interrupt by means of the CPCS flag in the TC_SR
registers.
Input pre-processing consists of capabilities to take into account rotary sensor factors such as
polarities and phase definition followed by configurable digital filtering.
Each input can be negated and swapping PHA, PHB is also configurable.
