27.1.6.7 Time-of-Flight Measurement Mode

This mode measures the time interval between a rising edge on the SMT_window input and a rising edge on the SMT_signal input. The SMTxTMR register starts incrementing on the rising edge of the window input. The SMTxTMR register value is written to the SMTxCPR register and the SMTxTMR register is reset on a rising edge of the signal input. In the event of two rising edges of the window signal without a signal rising edge, the SMTxCPW register will be written with the current value of the SMTxTMR register, which will then be reset. Refer to the figures below.
