27.1.6.5 Windowed Measurement Mode

This mode measures the period of the SMT_window input, selected with the WSEL bits, relative to the SMT clock. On the rising edge of the window input, the SMTxTMR register value is written to the SMTxCPR register. In Repeat mode, the SMTxTMR register is reset and continues to increment. The capture and Reset process repeats on the next rising edge. Refer to the figures below.
