27.4.3.2.2 Edge Detect (Hall Sensor) Mode

Edge Detect mode (MOD[3:0] = 0000) operates the same as Capture Every Edge mode (MOD[3:0] = 0011), except that capture interrupt events do not stop when the Input Capture Buffer Overflow Status (ICOV) flag becomes set. This allows a continuous stream of capture events to trigger interrupt events without the need to continuously empty the FIFO.
